The operation method of plate ice machine, includes the following steps：

1), booting by compressor, condenser 20 and expansion valve will exchange heat agent compressed, condense, vaporize be sent into evaporate The liquid supply pipe 6 of device, the agent that exchanges heat at this time is as refrigerant；

2), heat exchange agent enters in the unit plate body 1 of each evaporation 18 bottommost of veneer, by several circulation passages 3 by list The side of first plate body 1 flows to the other side, reaches the other side and is entered in the adjacent unit plate body 1 in top by the closure plate 5 communicated again, Thus snakelike bending flow path is carried out in several closure plates 5 and several unit plate bodys 1, makes evaporation veneer during heat exchange agent flows through 18 both side surfaces are freezed, and heat exchange agent finally flows out evaporator with persistent loop refrigeration operation by liquid back pipe 7；It will be followed by water pump 15 Fresh water in ring water tank 14 is delivered to sprinkler tank 17, then fresh water is sprayed to the two sides of each evaporation veneer 18 by spray nozzle On, fresh water is condensed on the wall surface of evaporation veneer 18 by heat absorption, and lasting spray makes the ice sheet on 18 wall surface of evaporation veneer gradually increase It is thick；

3), switch path direction, so that condenser 20 is switched to heat-absorbing action, evaporator switches to exothermic effects, will exchange heat The liquid back pipe 7 of evaporator is sent into agent, and the agent that exchanges heat at this time is as heating agent；

4), heat exchange agent enters in the unit plate body 1 of each evaporation 18 topmost of veneer, by several circulation passages 3 by list The side of first plate body 1 flows to the other side, reaches the other side and is entered in the adjacent unit plate body 1 in lower section by the closure plate 5 communicated again, Thus snakelike bending flow path is carried out in several closure plates 5 and several unit plate bodys 1, makes evaporation veneer during heat exchange agent flows through 18 both side surfaces heat, and heat exchange agent finally flows out evaporator by liquid supply pipe 6 and heats operation with short cycles；Water pump 15 stops at this time Machine, sprinkler tank 17 stops spraying fresh water to evaporation veneer 18, each to evaporate heat thawing contact surface ice body on 18 two side of veneer Slab is set to fall off；

5), slab is fallen on strainer 13, and plate ice product is discharged by ice mouth 12 by slide guide effect；It is remaining light in spray Water and trash ice are recycled to by strainer 13 in cyclic water tank 14.

Principle using 0 DEG C of icing of water cannot coexist because ice is monomineralic rock with its object, process of the water in crystallization In automatic despumation, only fresh water is freezing at this time, and impurity, air etc. are flowed out with water, thus be condensate in evaporation veneer 18 On ice have the characteristics that it is net transparent.

By the blocking or conducting set by closure plate 5, multiple unit plate bodys 1 connection of longitudinal arrangement is formed into multistage bending Circulation path, thus extend flow path length of the heat exchange agent in evaporator, extend delay duration of the heat exchange agent in evaporator, To realize the abundant effect of heat exchange agent, its utilization rate is improved, enhances heat transfer effect.

Heat exchange agent, which collides when flowing through circulation passage 3 with the fin 4 in it, to be contacted so that the turbulivity for the agent that exchanges heat increases By force, extend the heat exchange agent residence time, 4 surface of fin increases and heat exchange agent contact area.

The shape of fin 4 is more complicated, and heat transfer effect is better；The quantity of fin 4 is more, and heat transfer effect is better；The rule of fin 4 Lattice are bigger, and heat transfer effect is better；The spacing of fin 4 is smaller, and heat transfer effect is better.

Unit plate body 1 is made of aluminum alloy materials, and closure plate 5 is made of aluminum alloy materials.Use aluminum alloy materials with Heat exchange efficiency is improved, to optimize ice-making effect, promotes working efficiency.

There is the plate ice machine of veneer evaporator to has the following advantages for this：

Increase length of flow across, the residence time of heat exchange agent by the way that serpentine-like bending path is arranged, while flowing through pipe The fin 4 that variform is added on road inner wall increases the turbulence intensity of heat exchange agent, residence time by the complex road condition of flow path, To reach the heat exchange agent in pipeline heat exchange, final optimization pass heat transfer effect, improving heat exchanging efficiency are come into full contact with side wall.
