An embodiment of the present invention provides an air heat transfer apparatus, as shown in fig. 1, including:
the processing device comprises a product conveying channel 2 and a plurality of mutually isolated chambers 1, wherein the product conveying channel 2 is communicated with different chambers and can convey products to be processed into different chambers 1, and the chambers 1 are filled with air; here, the product transfer passage 2 communicates with each chamber 1, and is capable of transporting a product to be processed into any chamber 1, and is capable of receiving a product to be processed from any chamber 1 and transporting it into any other chamber 1. It will be appreciated that the product transfer channels 2 have an interface with each chamber 1 through which products to be processed can enter and exit the chamber 1.
Each chamber 1 is provided with a first temperature adjusting device 11 for adjusting the temperature of the chamber and a plurality of first temperature sensors A; a plurality of second temperature sensors B and second temperature adjusting devices 21 are arranged at the interfaces of the chamber 1 and the product transmission channel 2; here, as shown in fig. 1, the first temperature adjustment device 11 can cool or heat, and in order to increase the cooling and heating speed, a plurality of fans (one or more fans) may be disposed beside the first temperature adjustment device 11, so that the cooling and heating can be dissipated into the surrounding air as quickly as possible, and the temperatures of different positions in the chamber 1 can be made to be the same. In the chamber 1, air is the heat transfer medium. Here, when the first temperature sensor a is plural, the plural first temperature sensors a may be respectively located at different positions, so that the temperature in the chamber 1 may be measured more accurately. Also, when the second temperature adjusting means 21 is plural, the plural second temperature adjusting means 21 may be respectively located at different positions, so that the temperature at the interface of the chamber 1 and the product transfer passage 2 may be more accurately measured.
