Refrigeration system and operation method for making ice from brine

Abstract

The invention provides a brine-way ice making refrigeration system. The refrigeration system comprises a refrigeration compressor, an oil separator, a condenser, evaporators and an ice making pool. Anexhaust port of the refrigeration compressor is connected with an air inlet of the oil separator. An air outlet of the oil separator is connected with an air inlet of the condenser. A liquid outlet pipe of the condenser is connected with liquid inlet pipes of the evaporators. A throttling mechanism is arranged between the liquid outlet pipe of the condenser is connected with the liquid inlet pipes of the evaporators. The evaporators are arranged in the ice making pool or are arranged on the two sides or in the middle of the ice making pool. An ice melting pool is arranged on the side of the ice making pool. A water inlet of the upper portion of the ice melting pool and a water outlet of the condenser are connected to form a first circulation pipeline. A water outlet in the bottom of the ice melting pool and a water inlet of the condenser are connected to form a second circulation pipeline. Melt ice water of an ice making barrel is used as cooling water of the condenser, the condensation temperature of the condenser can be greatly lowered, and the cooling capacity of the refrigeration compressor is improved; and the ice shedding speed of the ice making barrel can be increased by using the cooling water of the condenser for the ice melting pool, and the ice yield of the system is further increased.

Description

technical field [0001] The invention relates to ice making equipment, a refrigeration system and an operation method for making ice with salt water. Background technique [0002] In the fresh-keeping process of aquatic products, short-term fresh-keeping by covering with crushed ice is still the main method. The ice making method is divided into salt water ice making and fast ice making machine ice. The ice made by the salt water ice making method is block ice, and the ice density is high, and it is not easy to melt; the ice made by the fast ice making machine is crushed ice or granular ice. , the density of ice is low and it melts easily. At the same time, whether using brine to make ice or rapid ice making to make ice, there must be a refrigeration process and a deicing process. Shortening the ice making time, shortening the deicing time and making reasonable use of the energy of the system are the key to improving the efficiency. In addition, the structure of the ice bu...

Problems solved by technology

The disadvantage is that the ice bucket of the same specification, this structure reduces the weight of the ice, and at the same time the shape of the ice is complicated, which increases the difficulty of deicing and prolongs the deicing time
