It can be understood that, the first salt solution can adopt the calcium chloride solution, the calcium chloride solution can still not freeze at 60 degrees below zero, compare, the sodium chloride solution is then frozen at 23 degrees below zero, the calcium chloride solution has stronger low temperature tolerance performance, can keep the mobility under the temperature of handing over the end, therefore the calcium chloride solution is used for carrying out the heat exchange for the first time with evaporimeter 100, and the sodium chloride solution in quick-freeze box 420 is used for contacting edible material, guarantee the security, avoid influencing the cooking after edible material unfreezes. Of course, other salt solutions can be used for the first salt solution, and the first salt solution is exemplified by calcium chloride solution.

When the split-type quick-freezing apparatus is operated, the liquid refrigerant and the pressure-reducing gas are mixed by the evaporator 100, and specifically, the liquid refrigerant and the pressure-reducing gas are mixed in the piping of the evaporator 100, and the evaporator 100 provides an evaporation space at a position where the liquid refrigerant and the pressure-reducing gas start to be mixed, and there is no gaseous refrigerant at the mixed position, that is, the partial pressure of the gaseous refrigerant is zero, so that the liquid refrigerant is inevitably evaporated to form the gaseous refrigerant. In the process, the heat of the calcium chloride solution in the liquid storage tank 410 is absorbed to prepare the low-temperature calcium chloride solution.

The mixed gas of the refrigerant in the gas state and the decompression gas flows along the gas return pipe 220 into the condenser 200, and the blower 300 drives the mixed gas to be introduced into the condensation chamber 201 of the condenser 200. The molecular sieve component 210 is arranged in the condensation cavity 201, and the molecular sieve component 310 is defined as a novel material capable of realizing molecular sieving, and has the pore diameter which is equivalent to and uniform with the molecular size, ion exchange performance, high-temperature thermal stability, excellent shape-selective catalytic performance, easy modification and multiple different types and different structures for selection. The molecular sieve assembly 210 is configured to allow the passage of the pressure-reduced gas while preventing the passage of the refrigerant, thereby achieving the separation of the mixed gas.

For example, the refrigerant is selected to be ammonia gas, the pressure reducing gas is selected to be hydrogen gas or helium gas, and the molecular diameter of the hydrogen gas is 0.289 nm, namely 2.89A. The molecular diameter of helium is 0.26 nm, i.e., 2.6A. The molecular diameter of ammonia gas was 0.444 nm, i.e., 4.44A. Therefore, the molecular sieve component 210 of 3A or 4A, such as a molecular sieve membrane, can be used to effectively separate hydrogen and ammonia, or helium and ammonia.

The nature of the liquefaction of the gaseous refrigerant is: after the relative humidity of the gaseous refrigerant reaches 100%, the gaseous refrigerant is necessarily liquefied. Therefore, after the mixed gas is separated, only the gaseous refrigerant remains in a part of the space of the condensation chamber 201, or the gaseous refrigerant and the liquid refrigerant exist at the same time, and when the blower 300 continuously introduces the mixed gas into the condensation chamber 201 of the condenser 200, the relative humidity of the gaseous refrigerant reaches 100%, and the gaseous refrigerant is automatically condensed into the liquid refrigerant.

The working process of the separation type quick-freezing equipment is illustrated by taking ammonia as a refrigerant and hydrogen as a pressure-reduced gas.

The mixed gas of ammonia and hydrogen is introduced into the condensation chamber 201 from the inlet of the condenser 200 by the blower 300. The hydrogen gas passes through the molecular sieve assembly 210 and flows out from the gas outlet, while the ammonia gas is blocked by the molecular sieve assembly 210 and is accumulated in the condensation chamber 201, and the concentration of the ammonia gas is increased continuously. According to the h-s diagram (enthalpy diagram) of ammonia gas, at 40 ℃, the saturation pressure Pt of ammonia is 15bar, the standby pressure of the separation type quick-freezing equipment is set to be 2Pt, namely 30bar, therefore, the concentration of the ammonia gas in the condenser 200 is continuously increased, when the concentration of the ammonia gas reaches 50%, namely the partial pressure of the ammonia gas reaches 1 Pt, the ammonia gas starts to be condensed to form liquid ammonia, and the liquid ammonia flows out of a liquid outlet. Liquid ammonia enters vaporizer 100 along liquid inlet tube 230, hydrogen enters vaporizer 100 along gas inlet tube 250, and the liquid ammonia and hydrogen are mixed in vaporizer 100. In the evaporator 100, the evaporator 100 is filled with light hydrogen, so that the partial pressure of ammonia is close to 0, and molecules of liquid ammonia enter the hydrogen to form ammonia, that is, the liquid ammonia is evaporated to absorb the heat of the calcium chloride solution in the liquid storage tank 410 to prepare the low-temperature calcium chloride solution. The mixed gas of ammonia and hydrogen then returns to the condenser 200 along the gas return pipe 220, and is circulated.

Calcium chloride solution flows in circulating pipe 430, in the inner chamber of quick-freeze box 420, calcium chloride solution and sodium chloride solution carry out the heat exchange through heat transfer part 432, make the sodium chloride solution in quick-freeze box 420 fall to the lower temperature, sodium chloride solution can keep liquid below zero, and sodium chloride solution is edible, sodium chloride solution contact is eaten material safe and reliable, utilize the freezing of microthermal sodium chloride solution quick realization edible material, realize the quick-freeze, and compare in liquid nitrogen quick-freeze cost reduction by a wide margin, satisfy the demand of large-scale operation. In addition, the traditional refrigeration circulation mode is changed by the separated refrigeration equipment, and the energy consumption required in the condensation process is lower, so that the production cost of the refrigeration system is reduced, and the separated refrigeration equipment has greater economic benefit.

It is understood that the throttling assembly 240 employs an electronic expansion valve, which is a throttling element that can control the flow of refrigerant in the refrigeration unit according to a preset program. The electronic expansion valve controls the voltage or current applied to the expansion valve through the electric signal generated by the regulated parameter, thereby achieving the purpose of regulating the liquid supply amount.
