Description

Technical Field

[0001] This invention relates to the field of food raw material sampling and testing technology, specifically a sampling and testing device for the initial processing of food raw materials. Background Technology

[0002] Food raw materials refer to the basic substances used in the production and processing of food; they can be natural or partially processed products. Legumes are one such food raw material, and they are popular due to their crisp texture and savory flavor after processing. In the initial processing of legumes, a blanching process is usually required to enhance their flavor and disinfect the harvested raw materials. Blanching involves briefly heating the legumes in hot water. After blanching, sampling and testing of the blanched legumes are necessary to monitor the disinfection effect and assess their quality.

[0003] The actual method for sampling and testing legume food ingredients is usually that the operator holds a container and scoops out the legume food ingredients from top to bottom in the holding box, and then tests the scooped portion of the legume food ingredients.

[0004] While the above sampling method allows for rapid sampling, the raw bean products are placed in a container. When operators scoop the raw bean products from the container from top to bottom, the products press against each other and are also subjected to pressure from the container. Furthermore, since the raw bean products have just undergone blanching and are softened, they are easily deformed under pressure, affecting the appearance of the processed products. Additionally, the sampling method cannot guarantee that the container is completely filled with raw bean products, resulting in significant variations in the sample size each time. This leads to unreliable test results and makes the samples unrepresentative. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a sampling and testing device for primary processing of food raw materials, comprising a conveying base plate, a horizontal slide rail fixed to the top of the conveying base plate, a movable plate connected to the horizontal slide rail via an electric slider, a holding box for holding raw materials connected to the top of the movable plate via a T-shaped plate, the T-shaped plate being inverted, sampling parts symmetrically arranged front and back on the horizontal section of the T-shaped plate, and reciprocating pushing parts arranged on the left and right sides of the top of the movable plate; the holding box and the T-shaped plate are connected by a snap-fit ​​assembly; the sampling part includes a limiting slide rail fixed to the horizontal section of the T-shaped plate, a mounting plate connected to the limiting slide rail via a limiting slider, and a limiting component connected to the top of the mounting plate. The container has a sampling tube embedded in the limiting seat. A lifting component is connected between the top of the moving plate and the limiting seat. The lifting component is used to lift the limiting seat and the sampling tube together. The container has two sets of sampling holes symmetrically opened at the front and back. Each set of sampling holes consists of multiple sampling holes arranged horizontally. The sampling part also includes a sealing component fixed on the container and corresponding to the position of each sampling hole. The reciprocating pushing part includes vertical plates symmetrically fixed on the top of the moving plate. L-shaped plates are fixed on the top of the two vertical plates. The vertical section of the left L-shaped plate is connected to a baffle near the side of the container by multiple compression springs. The vertical section of the right L-shaped plate is connected to a pushing plate near the side of the container by a hydraulic cylinder.

[0006] Preferably, the connecting component includes a vertical frame fixed to one end of the vertical section near the T-shaped plate on the top of the mounting plate, with limit strips symmetrically fixed inside the vertical frame, and a vertical moving block slidably connected to both the vertical frame and the limit strips, with one end of the vertical moving block away from the T-shaped plate connected to the limit seat.

[0007] Preferably, the locking assembly includes two sets of locking blocks fixed symmetrically to the top of the vertical section of the T-shaped plate. Each set of locking blocks consists of two locking blocks that are symmetrically arranged on the left and right. Each locking block and the container are provided with a slot. An inner moving rod is horizontally slidably connected in the slot. Multiple tension springs are connected between the inner moving rod and the side wall of the slot. A locking structure is provided at the bottom of the slot. A pressing block that slides through the side wall of the container is fixed at the top of the inner moving rod.

[0008] Preferably, the clamping structure includes a limiting protrusion fixed to the side of the slot and located at the position of the locking block, and a square protrusion provided on the side of the inner moving rod at the position corresponding to the limiting protrusion, and the T-shaped plate and the holding box are connected by the limiting protrusion and the square protrusion.

[0009] Preferably, the sealing component includes a through groove at the bottom of the container, the through groove communicating with the sampling hole, a sealing plate being slidably connected in the through groove, an inner spring being connected between one end of the vertical section of the sealing plate near the T-shaped plate and the side wall of the through groove, and a matching ramp being provided at the bottom of the sealing plate near the sampling hole, which is pushed by the sampling tube.

[0010] Preferably, the sealing plate has a pushing arc surface on its side inside the through hole. The pushing arc surface pushes the raw material upward, thereby preventing the sealing plate from damaging the raw material during the process of sealing the through hole.

[0011] Preferably, the lifting component includes a second hydraulic cylinder fixed to the top of the movable plate. A lifting plate is installed at the pushing end of the second hydraulic cylinder. Limiting rods are symmetrically fixed on the top of the movable plate and on both sides of the second hydraulic cylinder. The limiting rods slide through the lifting plate. A synchronous slide rail is fixed on the side of the vertical section of the lifting plate near the T-shaped plate. A transmission structure connects the side of the synchronous slide rail near the limiting seat through a synchronous slider. A limiting structure is provided on the top of the lifting plate.

[0012] Preferably, the limiting structure includes a pad fixed to the top of the lifting plate, and an L-shaped limiting plate fixed to the top of the pad. Both the vertical and horizontal sections of the L-shaped limiting plate are provided with multiple ball bearings.

[0013] Preferably, both vertical plates are symmetrically provided with horizontal sliding grooves, and connecting plates are slidably connected in the horizontal sliding grooves that are opposite to each other on the left and right sides. A bidirectional threaded rod is rotatably installed in the left vertical plate. The bidirectional threaded rod is threadedly connected to each connecting plate. A crank is fixed at the front end of the bidirectional threaded rod. Each connecting plate is connected to a friction plate on the side near each closed block through multiple connecting springs.

[0014] Preferably, a positioning seat is fixed at the top of the horizontal section of the T-shaped plate corresponding to the position of each sampling hole, and a matching seat is fixed at one end of the mounting plate corresponding to the positioning seat. A positioning pin is connected between the matching seat and the positioning seat at the corresponding position.

[0015] The beneficial effects of this invention are as follows: First, this invention uses a lifting component to lift the limiting seat and the sampling tube, so that the sampling tube can take samples from the bottom up through the sampling hole preset at the bottom of the holding box. Compared with the method of directly sampling from the top of the holding box using a container, this method can reduce damage to the raw materials of bean products, thereby ensuring the quality of the processed raw materials of bean products. At the same time, the pushing arc surface set on the side of the sealing plate can prevent the sealing plate from damaging the raw materials of bean products during the process of sealing the through hole, thereby further ensuring the quality of the processed raw materials of bean products.

[0016] Second, this invention employs a reciprocating pushing unit to reciprocate the lifting container, thereby ensuring a uniform distribution of bean food ingredients within the container. Furthermore, a friction plate drives the sampling tube inserted into the sampling hole to rotate continuously. This, combined with the left-right reciprocating movement of the container, ensures a uniform distribution of bean food ingredients within the sampling tube and guarantees sufficient filling of the tube, achieving quantitative sampling and ensuring the representativeness of the sample. Simultaneously, the use of multiple sampling holes increases the randomness of sampling, thereby ensuring the reliability of the test results.

[0017] Third, this invention uses a snap-fit ​​assembly to connect the T-shaped plate and the container. The quick snap-fit ​​method not only ensures the positioning accuracy of the T-shaped plate and the container, thus ensuring the accuracy of the sampling position, but also allows for quick separation of the T-shaped plate and the container. This facilitates the separation of the container and the T-shaped plate after transportation and makes it easy to pour out the bean food raw materials in the container. Furthermore, the snap-fit ​​method also improves the stability of the container during transportation. Attached Figure Description

Detailed Implementation

[0029] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0030] See Figures 1-2 A sampling and testing device for primary processing of food raw materials includes a conveying base plate 1, a horizontal slide rail 11 fixed on the top of the conveying base plate 1, a moving plate 111 connected to the horizontal slide rail 11 via an electric slider, a holding box 2 for holding raw materials connected to the top of the moving plate 111 via a T-shaped plate 112, the T-shaped plate 112 being inverted, sampling parts 3 being symmetrically arranged at the front and back of the horizontal section of the T-shaped plate 112, and reciprocating pushing parts 4 being arranged on the left and right sides of the top of the moving plate 111.

[0031] It should be noted that this invention can be used not only for sampling and testing of legume food ingredients, but also for sampling and testing of other nut food ingredients. The following is an example illustrating the sampling and testing steps of legume food ingredients using this invention.

[0032] This invention uses a sampling unit 3 to sample bean food ingredients placed in a holding box 2 after blanching, and to test the surface disinfection and sterilization of the bean food ingredients after blanching, thereby ensuring the blanching effect and food safety. Furthermore, the reciprocating pushing unit 4 can quickly push the holding box 2, thereby ensuring that the bean food ingredients are evenly dispersed by the left and right reciprocating movement of the holding box 2, while ensuring that the sampling unit 3 is filled with bean food ingredients during the sampling process, thus ensuring that the sampling unit 3 can take quantitative samples and that the samples taken are more representative.

[0033] Specifically, when the holding box 2 is filled with blanched bean food ingredients, the sampling unit 3 first takes a sample of the bean food ingredients in the holding box 2. During the sampling process, the reciprocating pushing unit 4 drives the holding box 2 to move back and forth, so that the bean food ingredients in the holding box 2 are evenly distributed while ensuring that the sampling unit 3 takes a quantitative sample of the bean food ingredients. After the sampling is completed, the bean food ingredients in the sampling unit 3 are taken out and tested. After the test is completed, the electric slider can drive the holding box 2 and the sampling unit 3 to move to the right together, so as to transfer the blanched bean food ingredients to the next processing position.

[0034] The container 2 and the T-shaped plate 112 are connected by a snap-fit ​​assembly 22. The snap-fit ​​assembly 22 includes two sets of locking blocks 221 fixed symmetrically to the top of the vertical section of the T-shaped plate 112. Each set of locking blocks 221 consists of two symmetrical locking blocks 221. Each locking block 221 and the container 2 are provided with a slot 222. An inner moving rod 223 is horizontally slidably connected in the slot 222. The inner moving rod 223 and the side wall of the slot 222 are connected by a snap-fit ​​assembly 222. Multiple tension springs are connected between the slots. A locking structure is provided at the bottom of the slot 222. A pressing block 224 that slides through the side wall of the container 2 is fixed at the top of the inner moving rod 223. The locking structure includes a limiting protrusion 225 fixed on the side of the slot 222 and located at the position of the locking block 221. A square protrusion is provided on the side of the inner moving rod 223 and at the position corresponding to the limiting protrusion 225. The T-shaped plate 112 and the container 2 are connected by the limiting protrusion 225 and the square protrusion.

[0035] By using the snap-fit ​​assembly 22 to snap-fit ​​the container 2 and the T-shaped plate 112, not only can the container 2 and the T-shaped plate 112 be quickly separated, thus facilitating the pouring of bean food raw materials, but the positions of the container 2 and the T-shaped plate 112 can also be quickly positioned, thereby ensuring that the sampling unit 3 can accurately sample the bean food raw materials contained in the container 2.

[0036] Specifically, before placing the bean food ingredients into the container 2, the container 2 is placed on the plane formed by the T-shaped plate 112 and the locking block 221. At the same time, the square protrusion is engaged with the limiting protrusion 225 by pressing the block 224. At this time, the container 2 can be stably connected with the T-shaped plate 112. After the T-shaped plate 112 and the container 2 are connected, the pressing block 224 is released. The square protrusion will move to below the limiting protrusion 225 due to the elastic force of the tension spring, and the limiting protrusion 225 will firmly lock the inner moving rod 223 and the container 2.

[0037] During disassembly, simply press all four pressing blocks 224 simultaneously to separate the container 2 and the T-shaped plate 112, and then tilt the container 2 using an external gripping and pushing device.

[0038] See Figure 3 , Figure 4 , Figure 7 and Figure 8 The sampling unit 3 includes a limiting slide rail 31 fixed on the horizontal section of the T-shaped plate 112. A mounting plate 311 is connected to the limiting slide rail 31 via a limiting slider. The top of the mounting plate 311 is connected to a limiting seat 312 via a connecting component 32. A sampling tube 313 is embedded in the limiting seat 312. A lifting component 33 is connected between the top of the moving plate 111 and the limiting seat 312. The lifting component 33 is used to lift the limiting seat 312 and the sampling tube 313 together.

[0039] The container 2 has two sets of sampling holes 21 symmetrically arranged front and back. Each set of sampling holes 21 consists of multiple sampling holes 21 arranged horizontally in a linear manner. The sampling part 3 also includes a sealing component 34 fixed on the container 2 and corresponding to the position of each sampling hole 21. The top of the horizontal section of the T-shaped plate 112 is fixed with a positioning seat 113 corresponding to the position of each sampling hole 21. The mounting plate 311 is fixed with a matching seat 114 at one end corresponding to the positioning seat 113. A positioning pin connects the matching seat 114 and the positioning seat 113 at the corresponding position.

[0040] The sampling unit 3 is used to sample the bean food raw materials in the holding box 2. Since the holding box 2 is provided with two sets of sampling holes 21, the representativeness of the sample can be increased by sampling at multiple random locations. Furthermore, the sampling method of passing the sampling tube 313 through the sampling hole 21 from bottom to top can reduce the pressure on the bean food raw materials and avoid damage to the bean food raw materials. At the same time, the positioning seat 113 and the matching seat 114 can quickly match the position of the sampling tube 313 and the sampling hole 21, thereby completing the sampling at any position of the sampling hole 21.

[0041] Specifically, when the container 2 is filled with blanched bean food ingredients, the operator pushes the mounting plate 311, connecting component 32, sampling tube 313, and limiting seat 312, so that the sampling tube 313 is aligned with the sampling hole 21 at the selected position. Then, the positioning pin is inserted into the corresponding matching seat 114 and positioning seat 113, fixing the positions of the mounting plate 311, connecting component 32, sampling tube 313, and limiting seat 312. Then, the lifting component 33 is controlled to lift the sampling tube 313 and limiting seat 312 upwards. At this time, under the action of the sealing component 34, The sampling tube 313 passes through the sampling hole 21 and is inserted into the bean food raw material. During the insertion process, the bean food raw material will enter the sampling tube 313. After the sampling tube 313 is inserted, the reciprocating pushing part 4 is controlled to push the holding box 2 back and forth, so that the gap of the bean food raw material in the sampling tube 313 is smaller and the sampling tube 313 is filled with bean food raw material. Then, the lifting part 33 can be used to control the sampling tube 313 and the limiting seat 312 to return to their original positions, and at the same time, the sealing part 34 seals the sampling hole 21 again.

[0042] See Figure 4 , Figure 7 and Figure 8 The sealing component 34 includes a through groove 341 at the bottom of the container 2, which is connected to the sampling hole 21. A sealing plate 342 is slidably connected inside the through groove 341. An inner spring 343 is connected between the vertical section of the sealing plate 342 near the T-shaped plate 112 and the side wall of the through groove 341. A matching ramp that is pushed by the sampling tube 313 is provided at the bottom of the sealing plate 342 near the sampling hole 21. A pushing arc surface is provided on the side of the sealing plate 342 inside the through groove 341. The pushing arc surface pushes the raw material upward, thereby avoiding damage to the raw material during the sealing process of the sealing plate 342 sealing the through groove 341.

[0043] The sealing component 34 is used to seal the sampling hole 21, thereby ensuring that the bean food raw materials in the holding box 2 will not leak. At the same time, the sampling tube 313, in conjunction with the ramp, can automatically push the sealing plate 342, thereby achieving the effect of unsealing the sealing plate 342 before the sampling tube 313 is inserted. After the sampling tube 313 has taken a sample, the sealing plate 342 will automatically push the excess bean food raw materials in the sampling hole 21 upwards, thus making the sealing and unsealing of the sampling process automatic.

[0044] Specifically, during the process of lifting the sampling tube 313 and the limiting seat 312 upward by the lifting component 33, the sampling tube 313 will first push the mating ramp, thereby causing the sealing plate 342 to move away from the sampling hole 21. At this time, the sampling tube 313 just enters the through groove 341. With the continuous upward lifting action of the lifting component 33, the sampling tube 313 will be inserted into the inside of the bean food raw material. Some of the bean food raw material will move into the sampling tube 313, while the rest of the bean food raw material will be blocked by the sampling tube 313 and remain in the holding box 2. Subsequently, when the sampling tube 313 and the limiting seat 312 are returned to their original positions by the lifting component 33, when the sampling tube 313 moves to the lower side of the sealing plate 342, the sealing plate 342 will quickly push the bean food raw material in the through groove 341 into the holding box 2 due to the elastic force of the inner spring 343.

[0045] See Figure 4 , Figure 6 , Figure 7 and Figure 8 The connecting component 32 includes a vertical frame 321 fixed to one end of the vertical section of the mounting plate 311 near the T-shaped plate 112. Limiting strips 322 are symmetrically fixed inside the vertical frame 321. A vertical moving block 323 is slidably connected to both the vertical frame 321 and the limiting strip 322. One end of the vertical moving block 323 away from the vertical section of the T-shaped plate 112 is connected to the limiting seat 312.

[0046] The connecting component 32 is used to stabilize the sampling tube 313 and the limiting seat 312 during the sampling process of the lifting component 33, and can also work with the mounting plate 311 to quickly adjust the position of the sampling tube 313 and the limiting seat 312.

[0047] See Figure 2 , Figure 4 , Figure 7 and Figure 8 The lifting component 33 includes a second hydraulic cylinder 331 fixed to the top of the movable plate 111. A lifting plate 332 is installed at the pushing end of the second hydraulic cylinder 331. Limiting rods 333 are symmetrically fixed to the top of the movable plate 111 and on both sides of the second hydraulic cylinder 331. The limiting rods 333 slide through the lifting plate 332. A synchronous slide rail 334 is fixed to the side of the vertical section of the lifting plate 332 near the T-shaped plate 112. A transmission structure is connected between the synchronous slide rail 334 and the limiting seat 312 via a synchronous slider. A limiting structure is provided at the top of the lifting plate 332. The limiting structure includes a pad 337 fixed to the top of the lifting plate 332. An L-shaped limiting plate 338 is fixed to the top of the pad 337. Multiple balls 339 are provided in both the vertical and horizontal sections of the L-shaped limiting plate 338.

[0048] In this example, such as Figure 5 As shown, in order to ensure that the transmission structure can be easily separated from the T-shaped plate 112 and the moving plate 111, the transmission structure adopts a lower sleeve block 335 fixed on the synchronous slider. The lower sleeve block 335 has an upper opening at the top, and the limit seat 312 has an inner insert block 336 fixed near the lower sleeve block 335.

[0049] The lifting component 33 is used to lift and return the sampling tube 313 and the limiting seat 312 to their original positions together. At the same time, the transmission structure connecting the synchronous slider and the limiting seat 312 can ensure that the two can be quickly separated during the disassembly and unloading of the container 2. The limiting structure can lift the container 2 in advance, so as to cooperate with the reciprocating push part 4 to push the container 2 back and forth, so that the bean food raw materials in the container 2 are evenly distributed, and the sampling tube 313 is fully filled with bean food raw materials to achieve the purpose of quantitative sampling.

[0050] See Figure 2 , Figure 3 , Figure 4 and Figure 7 The reciprocating push unit 4 includes vertical plates 41 that are symmetrically fixed to the top of the moving plate 111. Both vertical plates 41 have L-shaped plates 411 fixed to their tops. The vertical section of the left L-shaped plate 411 is connected to a baffle 412 near the side of the container 2 by multiple compression springs. The vertical section of the right L-shaped plate 411 is connected to a push plate 414 near the side of the container 2 by a hydraulic cylinder 413.

[0051] Both vertical plates 41 are symmetrically provided with horizontal sliding grooves. A connecting plate 415 is slidably connected in the horizontal sliding grooves that are opposite to each other on the left and right sides. A bidirectional threaded rod 416 is rotatably installed in the left vertical plate 41. The bidirectional threaded rod 416 is threadedly connected to each connecting plate 415. A crank is fixed to the front end of the bidirectional threaded rod 416. Each connecting plate 415 is connected to a friction plate 417 on the side near each closed component 34 through multiple connecting springs.

[0052] The reciprocating pusher 4 is used to reciprocate the container 2 lifted by the lifting component 33, thereby making the bean food raw materials in the container 2 evenly distributed. The friction plate 417 drives the sampling tube 313 inserted into the sampling hole 21 to rotate continuously. This, together with the reciprocating movement of the container 2, makes the bean food raw materials in the sampling tube 313 evenly distributed and ensures that the sampling tube 313 is fully filled with bean food raw materials, so as to achieve the purpose of quantitative sampling. At the same time, the bidirectional threaded rod 416 can drive the connecting plate 415 away from the sampling tube 313 to facilitate the disassembly of the container 2.

[0053] Specifically, when the lifting component 33 lifts the sampling tube 313 and the limiting seat 312 upwards, the L-shaped limiting plate 338, in conjunction with the ball bearing 339, pushes the container 2 upwards. Due to the locking action of the locking component 22, the container 2 moves upwards together with the T-shaped plate 112. Then, the container 2 moves into the pushing range of the reciprocating pushing part 4. The operator cranks the handle so that both the front and rear connecting plates 415 are close to the sampling tube 313. Then, the first hydraulic cylinder 413 drives the pushing plate 414 to push the container 2 and, in conjunction with the baffle 412 connected by the compression spring, makes the container 2 move back and forth. At this time, the sampling tube 313 moves back and forth with the container 2 and, in conjunction with the friction plate 417, makes the sampling tube 313 rotate frequently in the opposite direction. This prevents the bean food raw materials from getting stuck at the entrance of the sampling tube 313 and ensures that the sampling tube 313 is fully filled with bean food raw materials, thereby achieving the purpose of quantitative sampling.

[0054] It should be noted that since there is a sorting step for the bean food raw materials before blanching, the size of the bean food raw materials after blanching is roughly the same. Therefore, the sampling capacity under the condition of equal internal volume can be ensured by continuously rotating and moving the sampling tube 313 back and forth.

[0055] See Figure 9 The working steps of the present invention are as follows: First, point a is the position where the blanched bean food raw materials are poured into the holding box 2. First, the holding box 2 is filled with the blanched bean food raw materials. Point b is the position where the bean food raw materials are tested. The electric slider is controlled to move the holding box 2 to position b. Then, the operator pushes the mounting plate 311, connecting component 32, sampling tube 313 and limiting seat 312, so that the sampling tube 313 is aligned with the sampling hole 21 at the selected position, and the position of the sampling tube 313 is fixed by the matching seat 114 and the positioning seat 113.

[0056] The second step is to control the lifting component 33 to lift the sampling tube 313 and the limiting seat 312 upward after the positions of the two sampling tubes 313 are determined. At this time, the sealing component 34 will release the sealing effect on the sampling hole 21, and the sampling tube 313 will pass through the sampling hole 21 and be inserted into the bean food raw material. During the insertion process, the bean food raw material will enter the sampling tube 313.

[0057] Third, after the sampling tube 313 is inserted into the bean food raw material, the first hydraulic cylinder 413 drives the push plate 414 to push the holding box 2 and, together with the baffle 412 connected by the compression spring, the holding box 2 moves back and forth. At this time, the sampling tube 313 will move back and forth with the holding box 2, and, together with the friction plate 417, the sampling tube 313 will frequently rotate in the opposite direction, thereby preventing the bean food raw material from getting stuck at the entrance of the sampling tube 313 and ensuring that the sampling tube 313 is fully filled with bean food raw material.

[0058] Fourth step: After the sampling tube 313 has taken a sample, the lifting component 33 is controlled to move the sampling tube 313 and the limiting seat 312 downward and return to the initial position. When the sampling tube 313 moves to the bottom of the sealing plate 342, the sealing plate 342 will be immediately sealed by the elastic force of the inner spring 343. Then the sampling tube 313 filled with bean food raw materials is removed, and the bean food raw materials in the sampling tube 313 are poured out and tested to detect the surface disinfection and sterilization of the bean food raw materials after blanching.

[0059] Fifth step: After the test is completed, the sampling tube 313 is installed back in its original position. Then, the electric slider drives the holding box 2 and the sampling part 3 to move to the right together, so as to transfer the blanched bean food raw materials to point c. Point c is the position for pouring the bean food raw materials. Then, press the four pressing blocks 224 at the same time to separate the holding box 2 and the T-shaped plate 112. Then, the external gripping and pushing device is used to pour the holding box 2, so as to pour the bean food raw materials in the holding box 2 into the storage cylinder of the next process.
