Transfer pump for block and stem material

Abstract

The invention discloses a tuber material transfer pump which comprises a pump body and an impeller driving shaft mounted on the pump body, an impeller is mounted on the impeller driving shaft, the impeller has only one blade with a helical form cross section and a wrap angle equal or greater than 225 degree. The invention can be applied in the transfer of tuber material e.g. potato, fruits and vegetables with high transfer efficiency and no damage to the material.

Description

Technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to conveying equipment for tuber materials such as potatoes, fruits and vegetables. Background technique [0002] my country is rich in tuber resources such as potatoes, fruits and vegetables, and its finished products, especially French fries and potato chips made from potatoes, are one of the foods that consumers like very much. At present, most of the cutting (slicing) processing and transportation of tuber materials (such as potatoes, etc.) adopt mechanical methods. This type of processing method not only has low yield and poor appearance quality, but also has high labor intensity and low production efficiency. Difficult to adapt to the growing market demand for potato products. For this reason, there has been a method of using a pump as a power source for material transportation, and by means of hydraulic power to directly transport the material and push it...

Problems solved by technology

At present, most of the cutting (slicing) processing and transportation of tuber materials (such as potatoes, etc.) adopt mechanical methods. This type of processing method not only has low yield and poor appearance quality, but also has high labor intensity and low production efficiency. Difficult to adapt to the growing market demand for potato products

For this reason, there has been a method of using a pump as a power source for material delivery, and by means of hydraulic power to directly transport the material and push it to the cutting tool to complete the cutting and processing of the tuber material. The common impeller pump with multiple blades is still used. After the tuber material enters the impeller channel formed by the front and rear blades with the water flow, due to the different density of the transported material and the water flow, the material that follows the front blade into the impeller channel quickly. It is damaged by the impact of the blade surface of the rear blade. When this impact occurs at the outlet of the rear blade, the outlet end of the blade will cut and crush the material, causing a large amount of damage to the material, resulting in waste of raw materials and a decrease in the yield , in severe cases, the whole machine will not work normally
