Structure improvement and performance test of sweet corn peeling machine

Fresh sweet corn is sweet corn harvested at the late stage of milk ripening and early maturity. Sweet corn, with its unique taste, sweet, sticky, tender and fragrant characteristics, is known as "fruit corn". It has rich nutritional value, easy to chew, digest and absorb quickly, so it is more and more popular with consumers. Sweet corn should not be stored for a long time after harvesting. It is easy to deteriorate and cause nutrient loss. Its economic value will be reduced. It should be processed as soon as possible, usually no more than 6 hours. Mechanical peeling can peel off a large number of sweet corn husks in a relatively short time to ensure the quality of sweet corn. Because fresh sweet corn seeds are crisp and tender, slight collision will cause the rupture of the epidermis or internal crushing of the grain. The requirement of the peeler is higher than that of ordinary corn.

Microwave drying machinery and equipment

At present, the international application of sweet corn peeling equipment is mainly the product of A&K Company in the United States. The company's product productivity is high, suitable for countries with sparse population and relatively scarce labor force. When it is used in Chinese enterprises, the net stripping rate is low, generally 85%-90%, the damage rate is high, up to 4%-5%, and the price is about three times that of the domestic model, the investment cost is high, and Chinese enterprises seldom purchase and use it. With the development of sweet corn industry, sweet corn processing enterprises are in urgent need of peeling equipment for sweet corn peeling machine. The existing domestic peeling machine in China has a low peeling rate and a high breakdown rate. Moreover, there are still major quality problems in the corn peeling machine, such as poor safety, high failure rate and peeling equipment. Short life and poor quality seriously affect the enthusiasm of sweet corn processing enterprises to use peeling machines. Damage rate, peeling rate and productivity are the three main technical indicators of sweet corn peeling machine. These three technical indicators are interrelated and mutually restrictive. For enterprises, the damage rate is the most important indicator, which is directly related to the benefits of enterprises. In order to achieve the best peeling effect, our team cooperated with Jiangsu Nantong Hongjian Agricultural Machinery Co., Ltd. to improve the research and development of sweet corn peeling machine. Through a lot of test and observation on the old model, the most important damage rate index was solved, and three improvement measures were taken for some parts of the existing peeler.

(1) Improve the spiral convex edge transition corner of rubber roll surface; 2) Improve the material of rubber roll; The international application of sweet corn peeling equipment is mainly the product of A&K Company in the United States, which has high productivity, suitable for countries with sparse population and relatively scarce labor force.

The existing domestic peeling machines in China generally have low peeling rate and high breakage rate, and there are still major quality problems in corn peeling machines, such as poor safety, high failure rate, short life and quality of peeling equipment. The quantity difference has seriously affected the enthusiasm of sweet corn processing enterprises to use peeling machines.

In order to achieve the best peeling effect, our team cooperated with Jiangsu Nantong Hongjian Agricultural Machinery Co., Ltd. to improve the research and development of sweet corn peeling machine. Through a large number of experimental observations on the old model, the most important damage rate index was focused on. Three measures were taken to improve some parts of the existing stripper: 1) to improve the transition corner of spiral convex edge on the surface of rubber roll; 2) to improve the material of rubber roll;
