1, choice of materials
Processing of dehydrated carrot seed material should choose the skin smooth, color is bright orange red, healthy fresh carrots. Its length is 18 ~ 25 cm, both ends of uniform thickness, diameter of 2.5 ~ 4 cm, core to fine.
2, cleaning and finishing
Use clean water to remove sediment and other impurities, and then remove skin, cut green head and core, non core do meat. Peel method manual peeling, peeling machine and chemical peeling. Chemical peeling is the concentration of 3% ~ 6% alkali, temperature 80 ~ 90 ℃, dipping 2 to 4 minutes to soften the skin, but do not penetrate the inner organization of lye.
3, segmentation
To organize a good raw material into 0.6 ~ 0.8 cm square carrot granule or other shape, and then rinse with water.
4, Tang Piao
The aqueous solution of sodium bicarbonate carrot seed placed 0.1% in blanching of about 1.5 to 2 minutes, the specific size, according to the raw material particles and fresh degree. Blanching should quickly cooled with water clean. Then, Lek to the raw surface water or using a centrifuge to dry.
5, the dehydration
The material after processing, uniform Tanru drying sieve, quickly into the dryer dewatering. Drying room temperature control between 65 ~ 75 ℃, shall not exceed 75 ℃. Baked to a product at 6% moisture content, drying out quickly.
6, choose
Screen out debris, pick to the impurities and discoloration of the product. Operation should be fast, to prevent the product moisture.
7, packing
When packing the product moisture content of not more than 7.5%. for carton packaging, composite bag, seal.
