Potatoes deep processing machine

       Potatoes are native to the Andes of South America. The earliest cultivated history can be traced back to the southern part of Peru from about 8000 BC to 5000 BC. Potatoes are mainly produced in China, Russia, India, Ukraine, the United States and so on. China is the country with the largest output of potato in the world. Potato sex is cold and cold, it is a low temperature crop. The formation and growth of underground potato tuber requires loose, breathable, cool and moist soil environment. The temperature requirement of potato is: the temperature of the tuber growth is 16 ~18 C. When the ground temperature is higher than 25, the tuber stops growing; the growth temperature of the stem and leaf is 15 C ~25 C, and the growth is over 39 degrees centigrade.

       Potato starch, potato starch vermicelli, potato starch powder, potato powder, potato powder, potato starch, potato starch can process all kinds of food and snacks, potato starch and sugar syrup. Potato starch is the most commonly used product for deep processing of potatoes.

   

Here is a brief introduction to the processing of potato starch

1. Cleaning process and equipment

The main purpose is to remove the sediment on the surface of the material and remove the epidermis from the root of the material. The stone cleaning machine is to remove the hard impurities in the material. Cleaning of raw materials for starch production is the basis for ensuring the quality of starch. The better the cleaning, the better the quality of starch. Transportation is the transfer of materials to the next process, often conveying and cleaning functions. Commonly used transportation, cleaning, and stone removal equipment are: Hydraulic flute, spiral cleaning machine, squirrel cage cleaning machine, pulp blade cleaning machine, stone cleaning machine, squirrel cage cleaning machine, cylinder type cleaning machine, scraper conveyor and so on. According to the characteristics of soil and material, some of them can be selected for combination so as to meet the requirements of high cleanliness and convenient transportation.

2, raw material pulverization and equipment

The purpose of comminution is to destroy the structure of the material, so that the tiny starch granules can disintegrate and separate smoothly from the root. 

The requirement for comminution lies in:

1., as far as possible, the cells of the material will be broken and more free starch granules will be released.

2. is easy to separate. It is not desirable that the pomace is too thin. The fine slag is not conducive to the separation of starch from other components, and also increases the difficulty of separating fine slag.

3, screening process and equipment

Starch extraction, also known as slurry separation or separation, is a key step in starch processing, which directly affects starch extraction rate and starch quality. The crushed material is a fine fiber, the volume is larger than the starch granules, the expansion coefficient is greater than the starch granules, and the specific gravity is lighter than the starch granules. The crushed material is separated from the starch and the fiber is separated from the water.

4, washing process and equipment

The washing and concentration of starch is accomplished by a starch swirler. The hydrocyclone is divided into a concentrated cyclone and a washing refining cyclone. After screening, the starch slurry first passes through the concentrating cyclone, the bottom flow enters the washing and refining cyclone, and finally achieves the product quality requirement. The equipment is equipped with a complete set of automatic control system, using high quality swirling tube and optimal pipe arrangement scheme, which can make the concentration of starch milk removed by the last stage cyclone reach 23Be '. It is an ideal choice for starch washing equipment.

5, starch dehydration

Vacuum suction dehydrator is often used in potato starch. It can realize automatic feeding, automatic dehydration and automatic cleaning.

6, starch drying

The air dryer uses high speed flow of hot air to suspend wet starch and dry in the process of airflow. It has the characteristics of high heat transfer coefficient, large heat transfer area and short drying time.

7, starch cooling and screening packaging

After drying, the temperature of starch is relatively high. In order to ensure the viscosity of starch, it is necessary to cool the starch rapidly after drying. After cooling, the starch enters the finished product screen and enters the last packing process under the premise of ensuring the fineness and output of the product.https://www.cnstarchmachine.com/
