Description

Technical Field

[0001] This invention relates to the field of spice raw material processing, and in particular to a spice raw material cleaning and blanching equipment and process. Background Technology

[0002] Spices are commonly used seasoning ingredients, and star anise is a common spice. After being received by the factory, star anise needs to undergo preliminary processing, mainly including cleaning and impurity removal, and blanching. Currently, cleaning and blanching are mainly done manually and separately. The collected star anise is poured into a cleaning tank and then washed by stirring. After cleaning, the star anise is taken out of the cleaning tank and placed in a steamer. The star anise in the steamer is blanched by water steam. After blanching, the star anise is taken out and sent to the subsequent processing equipment.

[0003] The existing method involves three separate operations: washing, blanching, and conveying. This results in low overall efficiency and high manpower consumption. Therefore, there is an urgent need to design a device and process that can integrate washing, blanching, and conveying to improve the efficiency of star anise rough processing. Summary of the Invention

[0004] The purpose of this invention is to provide a spice raw material cleaning and blanching equipment and process, which realizes cleaning in the cleaning drum and can lift the cleaned star anise. During the lifting process, steam blanching is completed, realizing integrated processing. In addition, during the lifting process, impurities that were not removed during cleaning can be further screened out.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a spice raw material washing and blanching device, comprising a support frame and an inclined washing cylinder mounted on the support frame, an auger lifting structure being provided inside the washing cylinder, the auger lifting structure being connected to and driven by a motor outside the washing cylinder, a feed inlet being provided at the upper part of the lower part of the washing cylinder and a feed hopper being provided therewith, a steam inlet being provided on the washing cylinder, the steam inlet being provided with a steam generating device, a water injection hole being provided at the lower part of the washing cylinder and a water injection structure being provided therewith, the steam inlet being higher than the water level line inside the washing cylinder, and an opening at the upper end of the washing cylinder for conveying the washed and blanched star anise out.

[0006] Preferably, the auger lifting structure includes an auger shaft and auger plates, and the lower part of the auger shaft is provided with a material leakage hole that allows the octagon to pass through.

[0007] Preferably, the auger shaft, except for the portion with the material leakage hole, and the auger blades have a debris leakage hole that allows impurities to pass through but prevents the octagonal part from passing through.

[0008] Preferably, the portion of the water injection hole that communicates with the cleaning cylinder is provided with an interception net for intercepting impurities.

[0009] Preferably, the cleaning cylinder has a waste outlet at its lowest point, and a removable sealing block is fitted at the waste outlet.

[0010] Preferably, the cleaning cylinder has at least two steam inlet holes.

[0011] Preferably, a feed screen is provided at the feed inlet.

[0012] Another technical solution of the present invention provides a process for cleaning and blanching spice raw materials using the above-mentioned equipment, comprising the following steps: Step 1: Water injection. Inject cleaning water into the cleaning cylinder through the water injection structure and water injection hole. The water level should be lower than the lowest steam inlet hole. Step 2: Feeding. Pour the spices to be processed into the feed hopper. After passing through the feed inlet, they fall into the bottom of the washing cylinder and are completely immersed in the washing solution. Step 3: Rinse. Rinse the spices at the bottom of the rinsing tub for 3-5 minutes. Step 4: Lifting. The motor drives the auger shaft to rotate, which in turn lifts the cleaned spices through the auger blades. Step 5, Blanching: While the motor is starting in Step 4, 100-degree steam is continuously supplied into the cleaning cylinder through the steam generator and the air inlet. The steam is used to blanch the cleaned spices. Step six, discharge: The motor continues to lift until the spices are raised to the top of the opening of the washing cylinder and then discharged from the washing cylinder, completing the discharge of the spices.

[0013] Preferably, during the third cleaning step, the motor rotates in both directions, causing the auger shaft to rotate in both directions, which in turn causes the auger blades to move the spices back and forth in the cleaning solution for cleaning.

[0014] Preferably, after the material is discharged, the sealing block is pulled out, allowing the cleaning fluid and impurities to be discharged from the leakage hole.

[0015] The technical effects of this invention are as follows: 1. The cleaning process is carried out inside the cleaning drum, and the cleaned star anise can be lifted. During the lifting process, steam blanching is completed, realizing integrated processing. In addition, during the lifting process, impurities that were not removed during cleaning can be further screened out.

[0016] 2. The design of the auger structure is improved. The material leakage hole allows the poured spices to pass through the auger shaft into the lower part of the cleaning drum and then be completely cleaned in the cleaning solution. The impurity leakage hole allows the unwashed impurities to be discharged during the lifting process and fall into the bottom of the cleaning drum.

[0017] 3. The design of the water injection hole interception net can prevent impurities from entering the water injection pipeline.

[0018] 4. The design of the outlet with the sealing block ensures good cleaning, blanching and improvement effects, while also allowing wastewater and impurities to be discharged after cleaning.

[0019] 5. The process and equipment described in this application enable integrated cleaning, lifting, conveying, and blanching, thus optimizing the rough processing technology. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0025] like Figure 1-2 The present invention discloses a spice raw material washing and blanching device, comprising a support frame 1 and an inclined washing cylinder 2 mounted on the support frame 1. The washing cylinder 2 is characterized by having an auger lifting structure inside, which is connected to and driven by a motor outside the washing cylinder 2. A feed inlet 13 is provided at the lower upper part of the washing cylinder 2, and a feed hopper 8 is provided therein. The washing cylinder 2 also has a steam inlet 9, which is connected to a steam generating device. A water injection hole 7 is provided at the lower part of the washing cylinder 2, connected to a water injection structure. The steam inlet 9 is above the water level line 11 inside the washing cylinder 2. The upper end of the washing cylinder 2 is open for conveying the washed and blanched star anise. In some embodiments, the auger lifting structure includes an auger shaft 4 and an auger plate 5, and the lower part of the auger shaft 4 is provided with a material leakage hole 6 that allows the octagon to pass through.

[0026] In some embodiments, the auger shaft, except for the portion with the material leakage hole 6, and the auger blades 5, have a debris leakage hole 10 that allows impurities to pass through but not the octagonal part.

[0027] In some embodiments, the portion of the water injection hole 7 that communicates with the cleaning cylinder 2 is provided with an interception net for intercepting impurities.

[0028] In some embodiments, the cleaning cylinder 2 has a waste outlet at its lowest point, and a removable sealing block 12 is fitted at the waste outlet.

[0029] In some embodiments, the cleaning cylinder 2 has at least two steam inlet holes 9.

[0030] In some embodiments, a feed screen 14 is provided at the feed inlet 13.

[0031] Using the above-mentioned equipment, specific implementations are carried out, such as... Figure 3 The diagram shown is a process flow chart. The following are specific implementation examples.

[0032] Example 1 A process for cleaning and blanching spice raw materials includes the following steps: Step 1: Water injection. Through the water injection structure and water injection hole 7, cleaning water is injected into the cleaning cylinder 12. The water level line 11 is lower than the lowest steam inlet hole 9, specifically 10cm lower. Step 2: Feeding. Pour 20kg of star anise to be processed into the feed hopper 8. After passing through the feed inlet 13 and the discharge hole 6 of the auger shaft 4, it falls into the bottom of the cleaning cylinder 2 and is completely immersed in the cleaning solution. Step 3: Cleaning. Clean the star anise at the bottom of the cleaning drum 1 for 3 minutes. Specifically, the motor 3 rotates in both directions, causing the auger shaft 4 to rotate in both directions, which in turn causes the auger blades 5 to move the spices back and forth in the cleaning solution to clean the dust and particulate impurities attached to the star anise. Step 4: Lifting. The motor 3 drives the auger shaft 4 to rotate, which in turn drives the cleaned octagonal hoist through the auger blades 5. Step 5, Blanching: While the motor 3 is started in step 4, 100-degree steam is continuously supplied to the cleaning cylinder 2 through the steam generator and the air inlet 9. The steam is used to blanch the cleaned star anise. Step six, discharge: Motor 3 continues to lift until the spices are raised to the top of the opening of washing cylinder 2, then discharged from washing cylinder 2, completing the discharge of star anise. Step 7: Drain water and remove impurities. After lifting the material out, pull out the sealing block 12 to allow the cleaning fluid and impurities to be discharged from the leakage hole 10.

[0033] The star anise after discharge is collected, and the color of the star anise is manually observed to determine whether the blanching is qualified. After observation, the blanching is qualified. At the same time, the residual amount of particulate matter is observed. It is found that only one small particle (less than 5mm) remains, and the cleaning effect is qualified.

[0034] Example 2 Compared to Example 1, the difference in this example is that the cleaning time is 4 minutes, and after the first batch of star anise is cleaned and discharged, the second batch of star anise is added without changing the cleaning solution, and the cleaning, lifting and blanching and discharge operations are repeated. Then the third batch of star anise is added for cleaning, lifting, blanching and discharge operations, and then the water discharge and impurity removal operation in step seven is performed.

[0035] The three batches of star anise from Example 2 were observed and judged. All three batches of star anise were qualified in terms of blanching. The first batch had no particulate residue, the second batch had 3 particulate residues, and the third batch had 10 particulate residues.

[0036] In this embodiment, when the same batch of cleaning solution is used for multiple cleanings, it is easy to result in incomplete cleaning and residue of particulate matter, especially when three or more batches of cleaning are performed.

[0037] Example 3 Compared to Example 2, the main difference in this example is that the cleaning time is 5 minutes.

[0038] The three batches of star anise in this embodiment were observed. All three batches of star anise were qualified after blanching. The first batch had no particulate residue, the second batch had 1 particulate residue, and the third batch had 7 particulate residues.

[0039] The results from Examples 1-3 show that the equipment of the present invention can realize the integrated process of cleaning, lifting and conveying and blanching, improve the rough processing efficiency of star anise, and ensure good cleaning and blanching effects.

[0040] After completing the blanching and cleaning of a batch, if there is enough time, it is best to drain the water and remove impurities. If you need to rush the production schedule, you can perform two batches of cleaning and blanching before changing the cleaning solution. However, during the second cleaning, it is best to extend the cleaning time to 5 minutes to ensure a good cleaning and blanching effect.
