How to dry peppers with KINKAI dryer

Drying peppers by phase is the best practice at present. In the first phase, dry the pepper to reduce its moisture content from 75-80% to 50%, and then pile them up to sweat. In the second phase, dry the sweated pepper up. Piling pepper up for sweating is a very important step in the pepper drying process and has an great impact on quality and quantity of dried peppers and drying time.

Pepper becomes soft and inflated in the drying process. Piling peppers up for sweating plays a great role in improving quality of dried pepper. It will force pepper oil to permeate toward pepper's surface to make color of dried peppers uniform, red and smooth and to make water well-distributed. It only takes 20-40 hours to dry up pepper, and the number of yellow pepper is decreased. If not, it takes 63 hours to dry 1,000 kilograms of peppers at 40-60°C. Don't stir pepper too much in the second phase. Otherwise, damage rate will rise, resulting in decline of sales price. Drying time varies with the quantity and type of pepper.
