[0021] like Figure 1As shown, the hot and cold integrated capsule shell preparation device includes: a dehumidification heat pump system 100, a sol tank 200, a blank making machine 300, a dryer 400, a demoulding machine 500, a cutting machine 600 and a fan 700.

[0022] The dehumidification heat pump system 100 is connected to the air supply fan 700 in a loop to form a cooling cycle, and the dehumidification heat pump system 100 is connected to the sol tank 200 in a loop to form a heating cycle; the first outlet of the sol tank 200 is connected to the liquid inlet of the embryo making machine 300 by a pipeline, the outlet end of the embryo making machine 300 is connected to the inlet end of the dryer 400 by a pipeline, the outlet end of the dryer 400 is connected to the inlet end of the demoulding machine 500 by a pipeline, and the outlet end of the demoulding machine 500 is connected to the inlet end of the cutting machine 600 by a pipeline; the outlet end of the air supply fan 700 is connected to the air inlet of the embryo making machine 300 by a pipeline.

[0023] The sol stage requires hot water to be prepared for gelling, and the subsequent step of dipping the glue to make the embryo requires cold air to cool and dry the mold. The present application can utilize the dehumidification heat pump system 100 all-in-one machine to achieve one device to complete the cold and heat required in the two processes respectively.

[0024] In a possible implementation, the dehumidification heat pump system 100 includes: an evaporator 110, a condenser 120, a compressor 130 and a throttle 140; the evaporator 110, the compressor 130, the condenser 120 and the throttle 140 are connected in a loop, the first outlet of the evaporator 110 is connected to the inlet end pipeline of the compressor 130, the outlet end of the compressor 130 is connected to the first inlet pipeline of the condenser 120, the first outlet of the condenser 120 is connected to the inlet end pipeline of the throttle 140 The outlet end of the throttle 140 is connected to the first inlet of the evaporator 110; the evaporator 110 is connected to the air supply fan 700 circuit, the second outlet of the evaporator 110 is connected to the air supply fan 700 pipeline, and the second inlet of the evaporator 110 is connected to the air supply fan 700 pipeline; the condenser 120 is connected to the sol tank 200 circuit, the second outlet of the condenser 120 is connected to the sol tank 200 pipeline, and the second inlet of the condenser 120 is connected to the second inlet pipeline of the sol tank 200.

[0025] Workflow: The compressor 130 in the dehumidification heat pump system 100 sends the high-temperature and high-pressure refrigerant gas to the condenser 120. The high-temperature refrigerant in the condenser 120 exchanges heat with water and sends the heat to the sol tank 200 for sol. The high-temperature and high-pressure refrigerant vapor passes through the condenser 120 and becomes a high-temperature and high-pressure liquid. The high-temperature and high-pressure liquid passes through the throttle valve and becomes a low-temperature and low-pressure two-phase refrigerant. The refrigerant exchanges heat with water and transfers the cold to the air passing through the air supply fan 700. The air supply fan 700 introduces fresh air from the outside, filters it, cools it and dehumidifies it, and then sends the cold air to the embryo making machine 300 to cool and dehumidify the mold. At this time, the low-temperature and low-pressure two-phase refrigerant in the cold and hot integrated device absorbs heat and evaporates to become a low-temperature and low-pressure gas. After entering the compressor 130, it becomes a high-temperature and high-pressure gas and circulates back and forth.

[0026] In a possible implementation, a first circulation pump 150 is disposed between the second inlet of the evaporator 110 and the air supply fan 700 , and a second circulation pump 160 is disposed between the second inlet of the condenser 120 and the sol tank 200 .

[0027] In a possible implementation, the first outlet of the sol tank 200 is disposed at the bottom of the sol tank 200 .

[0028] In a possible implementation, a pressure pump 900 is provided between the first outlet of the sol tank 200 and the inlet end of the embryo making machine 300 .

[0029] In one possible implementation, it also includes: a metering tank 800, which is connected to the first inlet of the sol tank 200 by a pipeline, and the first inlet of the sol tank 200 is set near the top of the sol tank 200. The metering tank 800 is used to equip the materials required for preparing the capsule shell and transfer them to the sol in the sol tank 200.

[0030] In a possible implementation, an air duct is disposed at the inlet end of the air supply fan 700. The air duct is disposed vertically with the opening of the air duct facing upward.

[0031] First, gelatin, the main material for preparing the capsule shell, and related additives (such as plasticizer glycerin, thickener agar, refractive agent titanium dioxide, colorant tartrate and preservatives, etc.) are loaded into a metering tank 800 and transported to a sol tank 200. The hot water provided by the dehumidification heat pump is used for gelling. The general gelling temperature is 60°C-70°C. The sol-gelled colloid is sent to a blank making machine 300 through a pressure pump 900. Since the mold for preparing the capsule shell needs to be cooled and dried, a dehumidification heat pump system 100 is used to cooperate with a fan 700 to provide a cold air drying model. The sol treated in the sol tank 200 and the prepared capsule blank enter the dryer 400 to evaporate water to form a hard capsule shell. The demoulding is performed in a demoulding machine 500, and the capsule blank is cut into the required size in a cutting machine 600. Finally, the process is completed after sorting and packaging.

[0032] It should be noted that although the present application is used as an example to introduce a hot and cold integrated capsule shell preparation device as above, those skilled in the art will understand that the present application should not be limited thereto. In fact, the user can flexibly set various parameters according to personal preferences and / or actual application scenarios, as long as the design is reasonable.

[0033] In this way, the material for preparing the capsule shell enters the sol tank and is gelled using the hot water provided by the dehumidification heat pump system. After the sol, it is pumped to the embryo making machine through a liquid delivery pump. Since the mold for preparing the capsule shell needs to be cooled and dried, the dehumidification heat pump system is used in conjunction with the air supply fan to provide a cold air drying model, and then the sol produced in the sol tank is dipped. The prepared capsule embryo enters the dryer to evaporate the moisture and is made into a hard capsule shell, which is finally demolded and cut. During the preparation of the capsule shell, heat is conserved in the dehumidification heat pump system. According to a cold and hot integrated capsule shell preparation device of the present application, one system can be used to simultaneously provide cooling and heating for the capsule shell preparation process to increase energy utilization.

[0034] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
