Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] In the example, such as figure 1 , figure 2 , image 3 As shown, an alternate air supply tunnel type freezing device includes a built-in freezing tunnel. The material enters from the inlet 2 at one end of the speed-adjustable wrap-around conveyor belt 1 and passes out from the outlet 3 at the other end. Driven by the air supply fan 7, the cold air flows out from the air supply port 8 through the air supply channels 6 on the upper and lower sides of the conveyor belt 1 to cool the material. In the air outlet 8, the upper side is the down jet air supply slit 8-1, and the lower side is the upper floating air supply orifice plate 8-2. The lower jet air supply slit 8-1 is located at the top of the center of the conveyor belt, and is evenly distributed along the conveying direction. The jet gas flow rate is relatively high, which accelerates the g...

Abstract

The invention discloses an alternate air supply tunnel type freezing device. The alternate air supply tunnel type freezing device comprises a built-in freezing tunnel and a variable-speed surroundingtype conveying belt, and cold air supply ducts, air supply fans and air supply outlets are arranged on the upper side and the lower side of the conveying belt in the freezing tunnel. The alternate airsupply tunnel type freezing device is characterized in that an arch-shaped lower jet flow air supply slit is formed in the upper side of each air supply outlet, an upper blowing floating air supply pore plate is formed in the lower side of each air supply outlet, meanwhile, the positions of an upper air opening and an lower air opening are staggered front and back in the conveying direction, theairflow hedging phenomenon is avoided, and up-down alternate air supply and synchronous freezing are achieved. The alternate air supply tunnel type freezing device is reasonable in structure and highin freezing efficiency, equipment energy consumption is reduced while the material freezing quality is guaranteed, and the device has wide market prospects.

Description

technical field [0001] The invention relates to the field of freezing equipment, in particular to an alternate air supply tunnel type freezing device for quick freezing of aquatic products. Background technique [0002] At present, the refrigeration equipment used for aquatic products is generally divided into cabinet type and tunnel type. Among them, the tunnel type refrigeration device belongs to the streamlined production equipment, which is suitable for the production of large quantities of frozen aquatic products and is widely used. The main components of the tunnel freezer are low-temperature heat exchanger, air duct system, material conveying system, electrical control system and insulation wall. Its working method usually relies on the fan on the top of the tunnel to blow out the cold air that has been cooled by the heat exchanger, and conduct convective heat exchange with the aquatic products on the conveyor belt, so that the aquatic products can be quickly frozen. ...
