Description

Technical Field

[0001] This utility model belongs to the technical field of fish baking equipment, specifically relating to an energy-saving fish baking equipment with waste heat recovery function. Background Technology

[0002] Fish drying equipment is a specialized device used for drying fish, widely applied in the aquatic product processing industry. Taking air-source heat pump fish drying equipment as an example, it utilizes the reverse Carnot cycle principle, using a small amount of electricity to drive the compressor. High-pressure liquid refrigerant evaporates into a gaseous state in the evaporator after passing through an expansion valve, absorbing a large amount of heat energy from the air. The gaseous refrigerant is then compressed by the compressor into a high-temperature, high-pressure liquid state, which then enters the condenser to release heat. A fan then delivers the heat generated in the condenser to the drying chamber for heating and drying. Hot air circulates within the drying chamber, ensuring continuous and even heat transfer to the fish, removing moisture from the fish, which is then exhausted outside by an exhaust fan, achieving the drying purpose.

[0003] Specifically, during the processing of fish using baking equipment, a large amount of residual heat usually remains inside the cabinet after baking. This residual heat is mostly dissipated directly into the environment through heat dissipation and exhaust fumes, failing to be fully recovered and utilized. This not only causes serious energy waste, reducing the overall thermal efficiency of the equipment and significantly increasing energy costs such as electricity or gas, but also leads to an increase in the ambient temperature of the workshop, especially in summer when additional cooling equipment needs to be turned on to regulate the room temperature, further increasing the energy burden. At the same time, the direct emission of oil fumes and moisture carried by the residual heat will accelerate the corrosion of the equipment shell and the aging of surrounding components, increasing maintenance costs; moreover, the high temperature of the residual heat can easily cause finished fish that are not removed in time to become over-dried, affecting the taste and quality of the meat, and may even cause safety hazards in the operating environment due to the accumulation of residual heat. Utility Model Content

[0004] The purpose of this invention is to provide an energy-saving fish baking equipment with waste heat recovery function. This addresses the problem that a large amount of residual heat usually remains inside the cabinet after baking, and this heat is mostly dissipated directly into the environment through heat dissipation and exhaust, failing to be fully recovered and utilized. This not only causes serious energy waste and reduces the overall thermal efficiency of the equipment, significantly increasing the cost of electricity or gas, but also leads to increased ambient temperature in the workshop, especially in summer when additional cooling equipment is needed to regulate room temperature, further increasing energy consumption. Simultaneously, the direct emission of oil fumes and moisture carried by the waste heat accelerates the corrosion of the equipment casing and the aging of surrounding components, increasing maintenance costs. Furthermore, the high temperature of the waste heat can cause over-drying of finished fish that is not removed in time, affecting the texture and quality of the meat, and may even pose safety hazards to the operating environment due to the accumulation of waste heat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention involves installing a filter plate inside a processing chamber, sealing the assembly plate to the top of the chamber, and rotating a lead screw. This causes a linkage plate to move along the screw, simultaneously moving a pressure plate along an opening on one side of the positioning side plate. The pressure plate is then pressed and fixed to the assembly plate by its bottom surface. The fish are then baked by an electric heating element inside the baking chamber. The resulting flue gas is transported to the exhaust pipe via an air supply assembly. The filter plate then filters out fish impurities from the flue gas. The treated high-temperature flue gas enters the processing chamber, where the temperature continues to rise, preheating the fresh air inside the intake pipe. This improves the flue gas preheating and recovery effect, while also achieving energy savings. Attached Figure Description
