Orange pomace and peel drying method

Abstract

The invention discloses an orange pomace and peel drying method. The orange pomace and peel drying method is characterized by comprising the steps of performing rolling, namely feeding orange peels, kernels and pomace into a peel pressing oil machine to be rolled, feeding rolled orange peels and pomace into a smashing machine to form particle pulp with particle size ranging 8mm to 12mm, standing the particle pulp in a tank with a stirring device, adding 0.5-1% by total orange peel and pomace weight of lime, performing stirring for 30-40 minutes for standby application, feeding the orange peels and pomace mixed with the lime into a belt presser to squeeze the orange peels and pomace with 3-4 kilogram pressure, collecting the pressed orange peels and pomace for standby application, feeding the squeezed orange peels and pomace into a flashing type drying machine to be dried for 5-10 minutes at the temperature ranging from 400 DEG C to 40 DEG C and performing bagging, weighing, opening sealing and storage on dried orange peels and pomace. The dried orange peels and pomace are golden yellow in color and luster and free of bitter taste and can serve as a food and a feed additive, and the product usage is greatly improved.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to a method for drying citrus pomace peels. Background technique [0002] Citrus is an excellent fruit that people like. According to literature records, the current annual output of citrus in the world exceeds 100 million tons, and the annual output of citrus in my country exceeds 180 billion tons, and there is a trend of increasing year by year. Citrus will produce a large amount of pomace peels such as citrus peel and fruit stone in the process of processing fruit juice. Generally, the pomace peel accounts for about 30% of the total amount of citrus. Since the peels and pits of tangerines and red oranges are rich in protein, polysaccharides, trace elements and multivitamins, if they are not treated in a timely and scientific manner, they will soon become moldy and rot, emitting unbearable stench and polluting the environment Traditionally, citrus peels, cores, and pomace are ofte...

Problems solved by technology

However, a large amount of organic solvents are used in the production process, the production cost is high, the production process is complex, the production efficiency is low, and secondary pollution to the environment occurs.

Some people have also tried to process citrus peel residues to make feed additives by direct drying. Due to the special water-retaining structure (sponge body shape) of citrus peels and containing a large amount of pectin, not only the baking time is long, but the coal consumption is high. , often two tons of coal can't bake a ton of dry citrus peel residue, and often the outside of the citrus peel has been scorched, while the water content inside is still above 15%, and mildew is prone to occur during storage
