Roller dryer

Abstract

The invention discloses a roller dryer. The roller dryer comprises power devices, main racks, waste collecting devices, main bearing seats, semicircular supports, small waste rollers, small waste scrappers, small material distributing rollers, small material distributing scrappers, main rollers, upper dehumidifying hoods, material distributing spiral devices, scrapper devices, breaking and conveying devices and lower dehumidifying devices; the main bearing seats at two ends of the main roller are arranged on the main racks of the dryer; a semicircular support is arranged on each of the two main racks; and the small material distributing rollers, the small waste rollers, the scrapper devices and the material distributing spiral devices are arranged on the semicircular supports. By adopting the roller dryer, the integrity of cell granulates can be remained to the maximum extent during the processing process of whole potato powder, so that the products have flavor and taste close to those of original potato; and impurities such as stems and black spots in material processing can be removed, and thus the quality of the whole powder can be ensured.

Description

technical field [0001] The invention relates to a roller dryer for producing whole powder, which belongs to the field of food processing machinery. Background technique [0002] Potato powder has the advantages of steamed fresh potato flavor, less nutritional loss, good quality stability, convenient processing, easy forming, etc., so it is widely used in compound French fries (chips), instant mashed potatoes, fast food (or quick-frozen ) food, puffed food, and baby food are a variety of leisure and health food materials that are popular in the world; the roller dryer is the key production equipment; most of the existing roller dryers have three positive rollers on one main roller. A small roller, a reverse small roller, or two main rollers side by side; they generally beat the material into a slurry and then dry the roller during processing; for muddy materials with low water content and poor fluidity, For example, when drying mashed potatoes, the integrity of cell particle...
