Description

Technical Field

[0001] This utility model relates to the field of starch drying technology, specifically a device for recovering and utilizing waste heat from corn starch drying. Background Technology

[0002] Cornstarch, a common food ingredient, possesses various functions and uses, including thickening, stabilizing, and emulsifying. During cooking, cornstarch absorbs moisture upon heating, forming a colloid that increases the viscosity of food, making dishes or soups richer. In the preparation of pastries, puddings, and other foods, cornstarch stabilizes the structure, preventing ingredients from separating and maintaining the food's integrity and texture. However, cornstarch releases a significant amount of moisture during processing, which can affect its quality; therefore, drying is necessary.

It includes an outer shell with an inlet and an outlet at its upper and lower ends, respectively. The outer shell also has an air inlet pipe and an air outlet pipe. Inside the outer shell are a main chamber connected to the air outlet pipe and a secondary chamber connected to the air inlet pipe. A heat exchange component is mounted on the air outlet pipe, and a refrigerant discharge pipe is mounted on the heat exchange component, connected to the air inlet pipe. The advantages of this invention are: it solves the technical problem of high energy consumption in existing grain drying silos due to heat loss, achieving effective recovery and utilization of drying heat, reducing overall energy consumption, minimizing energy waste, lowering operating costs, and significantly expanding its application scope.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention enables efficient drying of corn starch using a drying tray and heating elements. Driven by a rotary motor, the rotating table allows the drying tray to rotate freely, achieving uniform drying. During the drying process, hot air, propelled by a pump, flows back to the base through a recovery chamber and return pipe. At this point, the hot air reheats the bottom of the drying tray through an annular groove and exhaust port. When the equipment is shut down, the exhaust port is closed by adjusting the motor-driven baffle plate.
