On June 28, Guoxin shipped a medium-sized drying oven to Shanxi Province. This oven can be used for drying all kinds of agricultural products. Shanxi customers use this 8P heat pump drying room for the drying of peppers.

Not only can we use the mesh belt dryer to dry the hot pepper, you can also choose drying hot pepper in oven when your output is not large, or when you are new to the project.



The pepper drying processing technology mainly includes: fresh pepper picking, transportation, storage, pre-processing, pepper drying, sorting, packaging, storage and other processes.

Drying Technology of hot pepper:

1. Choose high-quality peppers

If it is found to be obviously rotten and too soft to be squeezed, it is unqualified. This is very important. Good materials can make good things.

2. Processing

Picked peppers are washed and filtered again.

3. Put it into the drying tray of the box-type pepper dryer

Put the washed peppers in a dryer tray. The thickness of the stack is usually 20-30 cm. If the stack is too thin, the air permeability is good and the wind resistance is small. Although this is conducive to the exchange of heat, the hot air The contact time with the pepper will be relatively short, and the heat utilization rate will be reduced. If the buildup is too thick, it will increase resistance, making it impermeable to heat and reducing drying effect.

4. Use parameters of pepper dryer

The moisture of pepper is generally between 75%-85%, and the moisture content is relatively high. Set the temperature of the dryer at 40~60°C. At the beginning, the relative humidity is below 70%. After 5 hours, the relative humidity drops to 52%. After 12 hours, all relative humidity is below 40%. . Therefore, the drying efficiency of pepper depends on its own temperature, rather than the ability of hot air to carry moisture and remove moisture. From the perspective of ensuring the nutrient composition and yield of dried peppers, 60°C-70°C is the best.

5. Storage

Take out the dried peppers from the pepper drying equipment, and after the temperature reaches normal temperature, put them in a bag and place them in a ventilated place.
