Description

TECHNICAL FIELD

[0001] The utility model relates to pepper grain drying technical field, especially a kind of pepper grain low-temperature drying machine. BACKGROUND

[0002] Low-temperature drying helps to retain the natural flavor of pepper grains. The flavor of pepper grains mainly comes from volatile oils such as piperine and volatile oils contained therein. In a low-temperature environment, the loss rate of these flavor substances will be greatly slowed down. Low-temperature drying equipment usually includes a dryer, which continuously circulates and discharges low-temperature gas to complete the drying inside the equipment.

[0003] However, the current equipment has the problem of uneven hot air circulation. Since the low-temperature drying time is relatively long, if the hot air cannot be uniformly distributed in the drying chamber, it will cause inconsistent drying of the pepper grains, and the temperature stage rising effect is not formed in the drying process. For example, the pepper grains near the air inlet will continuously evaporate surface moisture due to sudden temperature rise, resulting in dry surface but still warm and humid inside, which ultimately affects the drying effect of the pepper grains.

[0026] Further, the circulating air duct 6 is arranged in a U shape, and the driving motor 301 is installed on both sides of the circulating air duct 6; the circulating lifting mechanism 3 includes: the transmission part 302 is symmetrically arranged on the partition plate 201, and the transmission end of one side of the transmission part 302 is connected with the driving motor 301; the lifting chain 303 is wound on the surface of the transmission part 302 and rotates in a ring shape, and the lifting chain 303 is used to connect and drive the fixing piece 4 to rotate in a ring shape; as shown in Figures 2-3 The space expanded by the circulating air duct 6 can install the driving motor 301 inside, the driving motor 301 on the side of the dryer 102 is completely contained, and the driving motor 301 on the other side extends to the outside, which is convenient for maintenance; the circulating lifting mechanism 3 is driven by the driving motor 301, the transmission part 302 drives the lifting chain 503 to rotate after being driven, the fixing piece 4 on the lifting chain 503 moves in a ring shape together with the lifting chain 503, thereby driving the tray 401 connected with the bearing structure 5 to move together, so that the trays 401 at different positions can be circulated and dried in different drying space 2 areas, and each tray 401 can complete the drying operation.

[0030] Specifically, as shown in the figure, Figure 3 the tray 401 first passes through the drying inlet 8 from top to bottom, gradually increases from the lowest temperature, and the bottom of the tray 401 is meshed, so that the gas can continuously penetrate, and then the evaporated gas on the tray 401 floats upwards and is extracted by the connecting pipe 701, so that a complete drying cycle operation is formed.
