The conveying net belt adopts servo control. According to different material varieties and cloth thickness, the frequency of the jigging motion i.e. , the alternate forward and backward motion of the conveying belt can be adjusted during its forward conveying process. Even if the cloth thickness is doubled on the basis of the current technology, there is no adhesion of materials and no occurrence of channeling.
The two-section type net belt conveying is adopted. At the front and rear sections, the conveying speed of net belt and rotation speed of fan are controlled independently to meet the requirements of processing different materials.
The initial freezing section is provided with air bypass pulse device to enhance the fluidized effect so as to realize the rapid freezing.
The ADS air automatic defrosting device is adopted to maintain the frost thickness of the evaporator always under 3mm and ensure that the quick-freezing machine can carry out 24-hour continuous production. The heat exchanging efficiency of the evaporator is greatly enhanced, and the power consumption of refrigerating compressor and fan is reduced. For quick-freezing output per unit, about20％of power consumption can be saved.
All parts are made of stainless steel, aluminum alloy and food level plastics, which comply with the food hygienic standards.
The high-efficiency cleaning device is provided to clean the residues on the net belt. All designs guarantee the facility and easy operation for cleaning and ensure hygienic safety of foods.
