Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a cream testing device. Background Technology

[0002] Cream is an oily dairy product extracted from milk or light cream. Its core component is milk fat, and it also contains small amounts of water, protein, lactose, and minerals. Its production process usually includes steps such as "separation of raw milk into light cream → sterilization → maturation → stirring → pressing", which ultimately forms a product with a delicate texture and rich flavor. It is widely used in baking, desserts, catering and other fields. Depending on the processing method, it can be divided into categories such as light cream, cream, and anhydrous cream.

[0003] As a frequently consumed dairy product, the testing of butter is not only related to product quality but also directly affects food safety and consumer health. The muffle furnace is the core equipment for butter ash content determination. Its core function is to remove organic components from butter by high-temperature burning, while retaining inorganic minerals, providing a basis for subsequent ash content calculation. Organic substances such as milk fat, protein, and lactose in butter will undergo oxidation reaction with oxygen in the air under the high temperature environment of 550-600℃ in the muffle furnace, eventually decomposing into volatile substances such as carbon dioxide and water vapor and escaping, leaving only inorganic minerals such as calcium, phosphorus, sodium, and potassium salts that cannot be burned.

[0004] The ash (inorganic minerals) after ignition is in a high-temperature, dry state in the muffle furnace. However, when it comes into contact with the outside air after being removed, it absorbs moisture due to "physical adsorption" and "chemical hygroscopicity." The ash after ignition is mostly fine powder with a large specific surface area and numerous micropores on its surface, possessing a strong physical adsorption capacity that can adsorb water molecules from the air. The inorganic minerals in the ash are mostly "hydrophilic substances" with polar groups in their molecular structure, which can form hydrogen bonds with water molecules, resulting in chemical hygroscopicity. Salts such as calcium chloride and sodium phosphate are easily deliquescent. The ash's hygroscopicity directly leads to "overweighting," which in turn causes a series of detection errors. Therefore, those skilled in the art have provided a cream detection device to solve the problems mentioned in the background art. Utility Model Content

[0005] 1. Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a cream testing device, comprising a testing box, a muffle furnace, a first motor, a travel plate, a second motor, and a grid frame. The testing box is sleeved on the outer side of one end of the muffle furnace. A grid frame is installed inside the muffle furnace, with equally spaced slots at the lower end of the grid frame. A container is placed at the upper end of the grid frame. A hydraulic rod is installed inside the testing box, with a travel plate at the lower end of the hydraulic rod. A measuring scale is installed at the upper end of the travel plate, and multiple sets of equally spaced top rods are installed at the upper end of the measuring scale. A cooler is installed at one end of the testing box, and a dryer with its output end penetrating the testing box is installed at the upper end of the testing box. A storage and retrieval port is opened at the front end of the testing box, and a second closing cover is rotatably installed at the opening of the storage and retrieval port. A first closing cover is installed at the opening of the muffle furnace.

[0008] Furthermore, the inside of the testing box is provided with a partition, the top rod is located on the travel path of the slot, the travel plate is embedded with symmetrically distributed sliding sleeves, and the inside of the testing box is provided with a guide rod that is slidably inserted into the sliding sleeves;

[0009] Specifically, the partition enhances the insulation effect and reduces the impact of the external environment on the interior of the testing chamber. During the movement of the slot inside the grid frame, it can be moved to the top rod to provide conditions for lifting the vessel. The travel plate slides on the outer wall of the guide rod through the sliding sleeve and is guided by sliding during longitudinal movement.

[0010] Furthermore, a support plate is provided at the lower end of the grid frame, a connecting rod is provided at one end of the support plate, a nut is provided on one side of the lower end of the connecting rod, an installation groove is provided inside the lower end of the muffle furnace, the connecting rod is located inside the installation groove, a guide rail is provided on the inner wall of the lower end of the installation groove, and a slider that is slidably sleeved on the outer wall of the guide rail is provided at the lower end of the nut.

[0011] Specifically, the support plate and connecting rod are supported by nuts, and the nuts are slidably supported inside the mounting groove by sliders, thus guiding the grid frame to slide.

[0012] Furthermore, a second motor is provided inside the mounting slot, and a screw threaded into the nut is provided at the output end of the second motor. A bearing seat is provided at the opening of the mounting slot, and one end of the screw is rotatably mounted inside the bearing seat.

[0013] Specifically, when the second motor drives the screw to rotate, one end of the screw receives rotational support inside the bearing housing, improving the rotational stability of the screw. At the same time, the mounting slot houses the support plate, preventing the mounting plate from affecting the opening and closing of the second closing cover.

[0014] Furthermore, the muffle furnace is provided with rotating seats at both the front and rear ends, and the closing plate is provided with rotating shafts rotatably installed inside the rotating seats at both the front and rear ends. The front end of the muffle furnace is provided with a motor 1 whose output end is connected to the rotating shaft.

[0015] Specifically, the rotating seat provides rotational support for the rotating shaft, so that the driving force of motor one drives the closing cover one to open and close at the opening of the muffle furnace through the rotating shaft.

[0016] Furthermore, a dehumidification port controlled by a valve is provided on one side of the upper end of the testing box, and a baffle is provided inside the testing box, with an airflow channel between the baffle and the lower inner wall of the testing box;

[0017] Specifically, the moisture and air inside the testing chamber are discharged through the vent, while the dry hot gas and cold air flow input by the dryer and refrigerator are blocked to prevent the airflow for safe use atmosphere restoration inside the testing chamber from directly acting on the vessels. The airflow for atmosphere restoration (cold airflow and dry hot airflow) flows through the airflow channel inside the testing chamber and muffle furnace.

[0018] 2. Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] This invention involves placing cream in a container and then subjecting it to high-temperature burning in a muffle furnace to remove organic components while retaining inorganic minerals. The muffle furnace's lid then automatically opens, and the grid frame supporting the container is automatically moved out of the furnace and into a testing chamber driven by a feeding structure. The testing chamber is isolated from the external environment. A longitudinally moving top rod penetrates the gaps within the grid, lifting the container. The container is then weighed by a measuring scale to detect the weight of inorganic minerals, which is compared to the weight before testing. This process avoids the absorption of external water molecules by the ash after burning, enabling effective and accurate testing.

[0021] Subsequently, the tested containers are removed, and the internal environment of the testing chamber is restored through a refrigeration unit and a dryer after reuse and closure to avoid moisture residue. This provides a stable testing environment for opening the muffle furnace, feeding, and weighing, ensuring the accuracy of continuous butter testing.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] Please see Figure 1-5 As shown, this embodiment is a cream testing device, including a testing box 2, a muffle furnace 5, a first motor 10, a travel plate 12, a second motor 15, and a grid frame 22. The testing box 2 is sleeved on the outer side of one end of the muffle furnace 5. The grid frame 22 is set inside the muffle furnace 5. The lower end of the grid frame 22 has equally spaced slots. The upper end of the grid frame 22 is set with a container 21. The testing box 2 is set with a hydraulic rod 17. The lower end of the hydraulic rod 17 is set with a travel plate 12. The upper end of the travel plate 12 is set with a measuring scale 20. The upper end of the measuring scale 20 is set with multiple sets of equally spaced top rods 30. One end of the testing box 2 is set with a cooler 1. The upper end of the testing box 2 is set with a dryer 8 whose output end passes through the testing box 2. The front end of the testing box 2 has a storage port 4. A second closing cover 11 is rotatably installed at the opening of the storage port 4. A first closing cover 3 is set at the opening of the muffle furnace 5.

[0037] The inside of the test box 2 is provided with a partition 9, the top rod 30 is located on the travel path of the slot, the stroke plate 12 is embedded with symmetrically distributed sliding sleeves 19, and the inside of the test box 2 is provided with a guide rod 18 that is slidably inserted into the sliding sleeve 19.

[0038] A support plate 23 is provided at the lower end of the grid frame 22. A connecting rod 13 is provided at one end of the support plate 23. A nut 28 is provided on one side of the lower end of the connecting rod 13. An installation groove 14 is opened inside the lower end of the muffle furnace 5. The connecting rod 13 is located inside the installation groove 14. A guide rail 25 is provided on the lower inner wall of the installation groove 14. A slider 27 that is slidably sleeved on the outer wall of the guide rail 25 is provided at the lower end of the nut 28.

[0039] The mounting slot 14 is equipped with a second motor 15. The output end of the second motor 15 is equipped with a screw 26 that is threaded into the nut 28. The opening of the mounting slot 14 is equipped with a bearing seat 24. One end of the screw 26 is rotatably mounted on the bearing seat 24.

[0040] The muffle furnace 5 is equipped with rotating seats 7 at both the front and rear ends, and the closing plate 2 is equipped with rotating shafts 29 rotatably installed inside the rotating seats 7 at both the front and rear ends. The front end of the muffle furnace 5 is equipped with a motor 10 whose output end is connected to the rotating shafts 29.

[0041] The upper side of the test chamber 2 is provided with a dehumidification port 6 controlled by a valve. The test chamber 2 is provided with a baffle 16 inside, and there is an airflow channel between the baffle 16 and the lower inner wall of the test chamber 2.

[0042] Based on the implementation steps of Example 1: The operator opens the closed cover 3 at the front of the testing box 2, places the container 21 containing the cream sample on the grid rack 22, weighs the empty container 21 in advance, closes the closed cover 3, starts the motor 10, and drives the closed cover 11 to close through the rotating shaft 29 and the rotating seats 7 at both ends of the muffle furnace 5, ensuring that the inside of the muffle furnace 5 is sealed. The muffle furnace 5 is heated to 550-600℃, the optimal temperature for the oxidation and decomposition of the organic components of the cream, and continues to burn for 2-4 hours. The organic components such as milk fat, protein, and lactose in the cream react with oxygen in the air, and volatile substances such as water vapor escape, leaving only inorganic minerals (ash) such as calcium, phosphorus, and sodium in the container 21. After the burning is completed, the muffle furnace 5 stops heating and waits for the internal temperature to drop below 200℃ to avoid the container 21 from cracking due to high temperature transfer. The motor 10 is started again, driving the closed cover 11 to open automatically, preparing for subsequent transfer.

[0043] Motor 215 starts, driving the screw 26 at the output end to rotate. One end of the screw 26 is fixed by the bearing seat 24 to ensure stable rotation. The screw 26 is threadedly engaged with the nut 28 on one side of the connecting rod 13 of the lower support plate 23 of the grid frame 22, and the slider 27 at the lower end of the nut 28 is sleeved on the guide rail 25 on the inner wall of the mounting groove 14. When the screw 26 rotates, the nut 28 slides horizontally along the guide rail 25, thereby driving the grid frame 22 and the container 21 containing ash above it from the inside of the muffle furnace 5 to the inside of the testing box 2 through the connecting rod 13 and the support plate 23. During the transfer, the testing box 2 is insulated from the external environment by the partition 9 to prevent the grid frame 22 from being damaged. When the container 21 comes into contact with the outside air, the ash absorbs moisture from the source. After the grid frame 22 is moved to the designated position in the test box 2, the hydraulic rod 17 is activated, pushing the lower stroke plate 12 upward. The measuring scale 20 and the top rod 30 at the upper end of the stroke plate 12 rise synchronously. The top rod 30 is located on the travel path of the slot at the lower end of the grid frame 22. During the rise, it can penetrate the gap of the slot and accurately lift the container 21 on the grid frame 22, avoiding the weight of the grid frame 22 from interfering with the weighing. After the container 21 is completely separated from the grid frame 22, the measuring scale 20 stably reads the total weight of "container 21 + ash". The ash weight is automatically calculated by the equipment control system to complete the accurate test.

[0044] After weighing is completed, the hydraulic rod 17 drives the stroke plate 12 to descend, the top rod 30 returns to its original position, and the vessel 21 falls back onto the grid frame 22.

[0045] The operator opens the closed cover 3, takes out the tested container 21, closes the closed cover 3, starts the cooler 1 to lower the internal temperature of the test chamber 2, causing the residual water vapor to condense into liquid water, starts the dryer 8, and inputs dry hot air. At the same time, the exhaust port 6 valve at the top of the test chamber 2 opens to expel the humid air. The baffle 16 inside the test chamber 2 can prevent the cooling and drying airflow from directly impacting the subsequently placed container 21. The airflow flows between the test chamber 2 and the muffle furnace 5 through the airflow channel between the baffle 16 and the lower inner wall of the test chamber 2, quickly restoring the internal dry environment and providing stable conditions for the next test, thereby improving the efficiency of batch testing.

[0046] After the butter is heated at high temperature in the muffle furnace 5, the container 21 containing ash is automatically moved to the detection box 2, which is isolated from the outside world, through the grid frame 22. After being lifted by the top rod 30, it is directly weighed by the measuring scale 20. The entire process avoids the ash from contacting the outside air, eliminating the problem of high weight caused by physical adsorption and chemical moisture absorption of ash from the root, and keeping the ash weight measurement error within a very small range. This ensures that the final test result can truly reflect the inorganic mineral content in the butter. The equipment achieves multi-stage automatic control through components such as motors and hydraulic rods 17. Motor 10 drives the muffle furnace 5 to automatically open and close the closing cover 21, eliminating the need for manual operation of the high-temperature furnace door. Motor 215, together with the screw 26 and nut 28, drives the grid frame 22 to automatically move in and out, replacing manual transfer of the high-temperature container 21. The hydraulic rod 17 drives the top rod 30 to automatically lift the container 21 to complete the weighing, reducing manual intervention steps. The automated design not only reduces the safety risks of operators coming into contact with high-temperature equipment;

[0047] The testing chamber 2 is equipped with a cooler 1, a dryer 8, and an airflow channel structure. After each test, it can quickly restore the internal dry environment. The cooler 1 lowers the temperature inside the testing chamber 2, causing residual water vapor to condense. The dryer 8 receives hot, dry airflow to absorb moisture and, in conjunction with the exhaust port 6, discharges humid air. The baffle 16 and airflow channel design prevent the restoring airflow from directly impacting the vessel 21. Simultaneously, it achieves airflow circulation within the testing chamber 2 and the muffle furnace 5. This design provides stable humidity control within the testing chamber 2, ensuring consistent environmental conditions for each test and preventing issues caused by fluctuations in humidity. To measure deviations and ensure consistency of cream test results across multiple batches, the muffle furnace 5 and the testing chamber 2 are connected by a nested structure. The opening of the muffle furnace 5 is sealed by a closing cover 11. Volatile gases such as water vapor generated during the burning process can be discharged through the ventilation structure of the muffle furnace 5, preventing gas leakage into the operating environment. The front access port 4 of the testing chamber 2 is equipped with a closing cover to further isolate external interference. At the same time, the slot at the lower end of the grid frame 22 is precisely matched with the position of the top rod 30, which can be adapted to different specifications of testing dishes 21, improving the adaptability of the equipment to the testing of different types of cream samples.

[0048] In traditional butter ash content testing, the ash after ignition needs to be removed from the muffle furnace 5 and transferred to a weighing device at room temperature. During this process, the ash easily absorbs moisture from the air, leading to an inflated weighing weight and consequently an overestimation of the calculated ash content. This device, by directly transferring the ignited container 21 into the sealed testing chamber 2 for weighing, completely avoids contact between the ash and the outside air, fundamentally solving this error problem and ensuring the accuracy and reliability of the test data. In traditional testing, manual transfer of the high-temperature container 21 can easily cause burns; furthermore, improper handling during manual transfer may cause the container 21 to tilt and ash to spill, resulting in sample loss. This device uses a motor-driven grid frame 22. The automatic transfer and hydraulic rod 17 automatic lifting and weighing design reduces direct contact between humans and high-temperature components, lowers safety risks, avoids sample loss caused by manual operation, and improves the success rate of testing. Traditional testing relies on the overall laboratory environment. In cases of high humidity, such as during the rainy season, a large number of water molecules in the air will continuously affect the ash weight, resulting in large fluctuations in the test results of the same batch of samples. It is impossible to determine whether the difference in results is due to the quality of the sample itself or environmental factors. The independent environmental control system of the testing chamber 2 of this equipment can maintain stable internal dry conditions without being affected by the external environment, so that the test results are only related to the quality of the sample itself, thus solving the problem of environmental interference.

[0049] In traditional testing, the muffle furnace 5 and weighing equipment are separate, requiring manual coordination of their operation. Furthermore, the lack of a dedicated guiding structure during transfer makes it prone to placement deviations of the vessel 21. This equipment, through the cooperation of the grid frame 22 and the guide rail 25 within the mounting slot 14, ensures precise movement of the grid frame 22. The corresponding design of the top rod 30 and the slot of the grid frame 22 guarantees that the vessel 21 can be stably lifted for weighing. The inner wall of the furnace is made of corundum, the outer shell is made of cold-rolled steel plate, and the closing cover 21 is made of heat-resistant stainless steel. The materials used include: the pivot 29 is made of 45# steel, corundum material which is resistant to high temperatures and has strong chemical stability, and will not react with substances produced during the scalding of butter, ensuring that the ash components are not contaminated; the cold-rolled steel plate shell can effectively insulate against heat, preventing the shell temperature from being too high and burning the operator; the 304 stainless steel closing cover 21 has good heat resistance and sealing performance, which can ensure the internal temperature of the muffle furnace 5 is stable during scalding and reduce heat loss; and the chrome-plated pivot 29 can improve wear resistance, ensuring that the closing cover 211 can be opened and closed smoothly for a long time and is not easy to rust.

[0050] The grid frame 22 is made of heat-resistant stainless steel, the support plate 23 is made of Q235 low-carbon steel, the connecting rod 13 is made of 45 steel, and the nut 28 and slider 27 are made of wear-resistant cast iron. The 316 stainless steel grid frame 22 is resistant to high temperature and corrosion, and can stably support the container 21 containing the cream sample. The grid structure facilitates heat circulation in the muffle furnace 5, ensuring uniform burning of the cream. The Q235 low-carbon steel support plate 23 has high strength and can provide stable support for the grid frame 22. The galvanized treatment can prevent the support plate 23 from rusting in the high temperature environment. The 45 steel connecting rod 13 has sufficient rigidity and can transmit the driving force of the motor 15. The wear-resistant cast iron nut 28 and slider 27 can reduce friction loss with the screw 26 and guide rail 25, extend the service life of the equipment, and ensure smooth movement of the grid frame 22.

[0051] The partition 9 is made of polyurethane insulation cotton, the baffle 16 is made of tempered glass, the evaporator of the cooler 1 is made of copper-aluminum composite material, the condenser is made of copper tubes with aluminum fins on the surface, the heating tube of the dryer 8 is made of stainless steel, and the fan impeller is made of engineering plastic. The copper-aluminum composite evaporator has high thermal conductivity and can quickly reduce the temperature inside the test chamber 2, causing water vapor to condense. The copper tube condenser has good heat dissipation and can ensure the stable operation of the cooler 1. The 304 stainless steel heating tube is resistant to high temperature and corrosion and can quickly generate dry hot airflow to absorb moisture inside the test chamber 2. The PP plastic fan impeller is lightweight and resistant to aging and can stably deliver airflow. Together with the airflow channel, it can quickly restore the environment inside the test chamber 2.
