Description

Chili Dryer

technical field

The utility model relates to the technical field of drying agricultural products, in particular to a chilli drying machine. the

Background technique

Peppers need to be cleaned and dried during the processing process. Pepper drying is one of the important links in the deep processing of peppers and their products. At present, the traditional natural drying method is the main method of drying peppers, which has low drying efficiency and poor sanitary conditions. The loss of chili peppers in the sky is serious, and manual drying is labor-intensive. The method of using chili dryers instead of traditional drying gradually appeared. When the dryers on the market are drying chili peppers, as the moisture decreases, the chili peppers become soft and smaller in size, forming The blanket-like pepper layer makes it difficult to turn the peppers during drying, which causes problems such as uneven drying, which seriously affects the drying quality and efficiency. the

In addition, the chili dryer is a drying equipment for batch and continuous production. The main heating methods include electric heating, steam heating, and hot air heating; The box moves back and forth, the hot air flows through the peppers, and the water vapor is discharged from the moisture-discharging hole, so as to achieve the purpose of drying. The water vapor is discharged while taking away the waste heat. It is measured that 40% of the heat is not effective. Utilization, greatly wasted energy, and production cost remains high. the

The heat taken by the pipeline is exchanged to the air intake pipeline for preheating and then enters the hot blast stove for waste heat recovery, and the water formed by the condensation of the cooled moisture can be used to wash the peppers, further saving water resources. the

Further, there are 3-11 conveyor belts. the

Further, the distance between the adjacent conveyor belts is 10-15cm, so as to ensure that the peppers will not be damaged due to falling from too high a height. the

Further, the conveyor belt is provided with holes for better ventilation and drying. the

In the pepper drying machine described in the utility model, the peppers fall to the lower conveyor belt through the upper conveyor belt, so as to realize accurate and thorough material turning and ensure the drying effect; through the longitudinal layer of material discharge, the space of the site is saved, thereby saving the investment in the factory area; through The heat exchanger recovers waste heat and condensed water, saving resources. To sum up, the utility model realizes a good drying effect by utilizing a small floor area, and can also recycle waste heat and steam at the same time, thereby further saving costs. the
