Description

Technical Field

[0001] The invention belongs to the technical field of freeze concentration, and in particular relates to a freeze concentration device. Background Art

[0002] The freeze concentration method in the prior art is a concentration technology that utilizes the solid-liquid phase relationship between a dilute solution and ice below the freezing point. There are two main methods: suspended crystallization freeze concentration and progressive freeze concentration. The principle of the suspended crystallization freeze concentration method is that when a dilute solution is frozen, the free small ice crystals suspended in the liquid are continuously removed to increase the liquid concentration. The principle of the progressive freeze concentration method is that when a dilute solution is frozen, as the ice layer is generated and grows on the cooling surface, the solute near the solid-liquid interface is removed to the liquid phase side, resulting in a concentration method in which the mass concentration of the solute in the liquid phase gradually increases. The existing freeze concentration method has a complex equipment structure, high equipment cost and production cost, and low efficiency. Summary of the invention

[0033] In one embodiment of the present invention, each heating panel of the tank container group is located between two cooling panels, for example, the heating panel 2 is located between the cooling panels 1 and 3 .

[0034] In one embodiment of the present invention, each heating panel and cooling panel of the tank container group has a gap at the lower end thereof for connecting adjacent tank cells. When the lower cover plate C of the tank container group is sealed and combined with its lower end, each tank cell of the tank container group is a connecting (container).

[0035] In one embodiment of the present invention, the lower cover plate of the tank container group is moved up and down by a screw rod 23, a motor 22, and a control system 21 to achieve sealing combination or separation with the lower end of the tank container group.

[0036] In one embodiment of the present invention, an ice support rack 12 is provided at the lower end of the trough grid of the trough container group, and the ice support rack 12 is locked together with the lower end of the trough grid of the trough container group through an ice support rack lock 17.

Then, after starting the heating switch in the control system 21 (the heating element provides the heat source or the heat source medium such as runny nose provides the heat source), the control switch of the motor 22 is started again, and the lower cover plate C moves downward a short distance: the edge 24 of the solution collection tank on the lower cover plate C is not separated from the protective cover 18, so that a narrow sealed space is formed between the lower cover plate C, the edge 24 of the solution collection tank, the protective cover 18, and the lower end of the tank grid group. The solution falls into the solution collection tank through the ice support rack 12, and flows out from the solution outlet 13, and the solution is received in sections to obtain solutions of different concentrations.
