Operation method for separating crust from seeds of tomato paste by disk huller

Abstract

The invention discloses an operation method for separating a crust from seeds of tomato paste by a disk huller. The operation method comprises the following steps: the water content of the fed tomato paste is about 10-20 percent, an inclined packing auger provides 2.2 KW power input with the diameter of 650 mm and the power of 17 KW to grind the disk huller at a rated speed; and a manual handle is used for firstly adjusting a grinding disc distance to be 5 mm and a feeding amount to be about 0.8 ton per hour, and then adjusting the grinding disc distance to be 3 mm to feed the ground materials by 0.4-0.6 ton per hour for once or twice so as to fully separate the crust form the seeds of the tomato paste. The invention overcomes the defect that the prior art can not finish separating the tomato crust form the tomato seeds in a device, adjusts the grinding disc distance of the disk huller by controlling the feeding amount of the tomato paste and grinds the tomato paste twice so that the separation effect of the crust from the seeds of the tomato paste can reach over 96 percent.

Description

technical field

[0001] The invention relates to a method for separating the skin and seeds of tomato paste, in particular to achieve the separation of the skin and seeds of tomato paste through a mechanical equipment operation method. Background technique

[0002] Tomato waste is a by-product of tomato paste processing, mainly tomato skin and tomato seeds. Among these waste residues, tomato skin is not only rich in calcium, magnesium, phosphorus, potassium, sodium and other mineral elements, but also contains lycopene; tomato seeds are ideal raw materials for nutrients such as vegetable oils, unsaturated fatty acids, and high-lysine proteins. At present, the waste residue of tomato paste seeds in my country has reached more than 100,000 tons. Therefore, in order to extract nutrients from these waste residues, people have developed a variety of cleaning and separation devices for tomato waste residue, skin and seeds. Chinese patent (Patent No.: 00126542.3) discloses a separ...
