Alternatively, the gas outlet 14 is arranged at the top of the enzymatic reactor 1 to facilitate the outflow of the gas and the solid cannot easily reach the gas outlet 14. The heating band 3 is wound on the outer side wall of the enzymatic reactor 1 to heat and keep warm the reaction cavity and create a suitable temperature environment for the enzymatic reaction. In addition, after the enzymatic reaction stage, the heating band 3 is heated to above 100℃, the material enters the hot drying stage, and the evaporated water and the generated volatile gas of the material are collected by the collection assembly, which can be a gas collector or a condensate water collector 8 and the like, which is not limited herein as long as the product can be collected.

For example, the condenser pipe 7 adopts a water cooling mode to condense the water vapor in the pipe, the condenser pipe 7 is arranged in the cooling cavity of the cooling pipe 13, and cooling water is introduced into the cooling cavity to condense the water vapor in the condenser pipe 7 into water on the inner wall of the condenser pipe 7.

[0046] According to one embodiment of the present application, the collecting assembly further comprises an air pump 9 connected to the side of the condenser tube 7 close to the condensate water collector 8 to suck the air in the system. It can be understood that in order to facilitate the air in the reaction chamber to flow to the condenser tube 7 through the air guide tube 6, the air pump 9 is arranged to suck the air in the condenser tube 7 to form a negative pressure, so that the air in the reaction chamber flows out through the air outlet 14.

[0049] According to one embodiment of the present application, the enzymatic thermal drying system further comprises a control panel 12 arranged on the outer wall of the enzymatic reactor 1, which is used to control the reaction time of the enzymatic reactor 1 and the temperature of the temperature increasing heating belt 3. It can be understood that the control panel 12 can control the start and stop of the driving member 5 to control the rotation of the crushing stirring paddle 4 and the reaction efficiency of the enzymatic reactor 1. At the same time, the heating temperature of the temperature increasing heating belt 3 can be controlled to control the reaction temperature.

[0050] As Figure 2As shown, the embodiment of the present application provides a method for operating an enzymatic thermal drying system, which includes an enzymatic reactor, a temperature-increasing heating belt, a collection assembly, a cooling tube, a condensate water collector, an air pump, a crushing stirring paddle, a driving member and a control panel. The enzymatic reactor is provided with a reaction cavity, an inlet and an outlet connected to the reaction cavity. The temperature-increasing heating belt is wrapped around the outside of the enzymatic reactor. The collection assembly is connected to the outlet. The collection assembly includes a gas guide tube and a condenser tube. One end of the gas guide tube is connected to the outlet. One end of the condenser tube is connected to the end of the gas guide tube away from the outlet. The cooling tube is provided with a cooling cavity, a water inlet and a water outlet connected to the cooling cavity. The condenser tube is arranged in the cooling cavity. The condensate water collector is arranged at the end of the condenser tube away from the gas guide tube. The condensate water collector is provided with a water collecting cavity connected to the condenser tube. The air pump is connected to the condenser tube. The crushing stirring paddle is rotatably arranged in the reaction cavity. The driving member is arranged in the enzymatic reactor. The output end of the driving member is connected to the crushing stirring paddle. The control panel is arranged on the outer wall of the enzymatic reactor. The method for operating the enzymatic thermal drying system includes the following steps:

[0051] Step one, 5-20 g of enzyme preparation is mixed with per kilogram of kitchen garbage to form a sample. The sample is put into the reaction cavity from the inlet. The driving member is started to drive the crushing stirring paddle to crush and stir the sample. It should be noted that the weight of the sample can be adjusted according to the actual situation. For example, 10-40 g of enzyme preparation is mixed with two kilograms of kitchen garbage to form a sample. The amount of enzyme preparation mixed with per kilogram of kitchen garbage can be 5 g, 10 g or 15 g, etc. which can be adjusted according to the organic matter content of the kitchen garbage. It can be understood that the driving member drives the crushing stirring paddle to stir the sample to make the kitchen garbage and the enzyme preparation mix uniformly and the crushing particle size is appropriate to improve the reaction efficiency.

[0052] Step two, the control panel starts the temperature-increasing heating belt. The temperature-increasing heating belt is heated to the temperature of the enzymatic reaction stage. The control panel is set to control the reaction time of the enzymatic reaction stage. The sample is reacted under the stirring of the crushing stirring paddle. The cooling water is fed from the water inlet and discharged from the water outlet. The air pump is started.

[0053] Step three, after the reaction time of the enzymatic reaction stage is set, the temperature-increasing heating belt is heated to above 100℃. The sample enters the thermal drying stage. The water evaporated from the sample is collected by the condensate water collector. It can be understood that the temperature-increasing heating belt heats the material in the reaction cavity to an appropriate temperature and keeps the temperature to improve the enzymatic reaction rate. In addition, after the end of the enzymatic reaction stage, the temperature-increasing heating belt is heated to heat and dry the reacted material in the reaction cavity. By wrapping the temperature-increasing heating belt around the outside of the enzymatic reactor, the step of taking out the sample for the thermal drying stage is avoided, and the operation complexity of the enzymatic reaction stage and the thermal drying stage is reduced.

[0054] Step four, the temperature-increasing heating belt stops heating. The temperature of the enzymatic thermal drying system is restored to room temperature.

[0055] Step five, the temperature of the enzymatic thermal drying system is recovered to room temperature, the broken stirring paddle stops working, the cooling water stops feeding, and the air pump stops working.

[0056] In one embodiment, the enzymatic reaction stage temperature is 50-70℃, and the enzymatic reaction stage reaction time is 4-6 hours; the thermal drying stage is set to a temperature of 100-120℃, and the thermal drying stage lasts for 4-8 hours. It can be understood that the enzymatic reaction stage reaction temperature is lower to achieve faster reaction rate while avoiding premature entry into the thermal drying stage. When there is more kitchen waste, the enzymatic reaction stage reaction time is longer, which can be 6 hours. Conversely, when there is less kitchen waste, the enzymatic reaction stage reaction time can be shorter, for example, 4 hours. The thermal drying stage is set to a higher temperature to make the sample enter the thermal drying stage, evaporate harmful substances, and discharge them to the collection assembly for collection.

[0057] In one embodiment, the enzyme preparation is mixed and prepared by carbohydrate enzymes, lipases and proteases, and the content of carbohydrate enzymes, lipases and proteases in the enzyme preparation is 10%-30%, wherein the carbohydrate enzymes are mixed and prepared by starch amylase, saccharifying amylase, xylanase, cellulase, β-glucanase, etc. in a certain proportion.
