Mouth is connected with centrifugal blower, and the wind direction of centrifugal blower is vertical with stack area, and the top of stack area is higher-pressure region, the lower section of stack area
For low-pressure area, it is equipped with spiral channel in stack area, is equipped with aperture on the interior plate and outer panel of spiral channel.
Further improvement of the utility model is that the wind of air inlet enters heat exchanger bottom, is cooled down by heat exchanger
Gas afterwards is sent into rapidly at the top of stack area by centrifugal blower, runs through spiral channel from top to bottom, the top of stack area is formed
Wind a part of higher-pressure region, higher-pressure region is entered in spiral channel by the aperture on inside panel, after another part heat absorption heating
Air-flow, be again introduced into heat exchanger bottom after low-pressure area, constitute circulation.
Further improvement of the utility model is, enters spiral channel by aperture on interior plate and outer panel
Wind, sent vertically downward with centrifugal blower to product surface high wind, form local whirlpool in the space of foraminous conveyer surface-closed
Stream.
The utility model has the advantages that
Temperature in freezer is from -30 ° hereinafter, and the temperature after over-heat-exchanger is reduced to -35 ° to -42 °C, efficient spiral shell
Rotation instant freezer uses to be set on efficient centrifugal blower, the underlying mounting means of heat exchanger, so that low-temperature circulating wind is above product
Product is passed through vertically downward, and the wind of centrifugal blower vertically blows to product, and heat exchanger effectiveness is significantly larger than the heat that horizontal wind carries away
Amount, low energy consumption, greatly shortens freeze-off time, maximumlly ensure that the quality of product, improves the efficiency of equipment.And it returns
Air-flow after temperature sucks below heat exchanger, is worked by such endless form, centrifugal blower quantity is few, and low energy consumption, wind pressure
Height, it is high-efficient, and can be avoided product and blown off ground, it is provided with aperture on interior outer panel, wind is mended by aperture, is produced with passing through
The high wind on product surface forms local eddy currents in the closed space of belt surface, and aggravation promotes product sufficient heat exchange, and shortening is freezed
Efficiency is freezed in time, raising.
