What is modified starch?
Modified starch is a modified starch. This starch has some special physical and chemical properties, which can be added to food formulations to give foods better performance when processed or consumed. As long as it is edible, its physiological function is no different from ordinary starch, and it can be eaten by children.
On the basis of the inherent characteristics of natural starch, in order to improve the performance of starch, expand its application range, use physical, chemical or enzymatic treatment to introduce new functional groups on starch molecules or change the size of starch molecules and the properties of starch granules. Thereby changing the natural characteristics of starch (such as: gelatinization temperature, thermal viscosity and stability, freeze-thaw stability, gel strength, film formation, transparency, etc.), making it more suitable for certain application requirements. This type of starch, which has undergone secondary processing and changes its properties, is collectively referred to as modified starch.
Working principle of modified starch special dryer:
This machine is a novel horizontal intermittent vacuum drying equipment. The wet material is evaporated by conduction. The scraper stirrer continuously removes the material on the hot surface and forms a circulating flow in the container. After the water evaporates, it is extracted by the vacuum pump. .
Performance characteristics of modified starch special dryer:
◎This machine adopts large-area interlayer heating method with large heat transfer surface and high thermal efficiency.
◎The machine is set to stir, so that the material forms a continuous circulation state in the cylinder, which further improves the uniformity of heat of the material.
◎The machine is set to stir, so that the slurry, paste and paste materials can be dried smoothly.
Analysis of the shortcomings of the vacuum dryer:
The jaw dryer has great limitations, especially if the operation is wrong, the wet article will cause the inlet part to be blocked, which reduces the carrying capacity, and in order to be well relieved, we need to spend a lot of processing time. Of course there are other flaws.
Defects in the dryer:
1. Vacuum dryer manufacturer introduces noise if it handles large particles, and falling particles may cause various effects, but if accurate temperature control is provided, especially if the material characteristics change, there will be Certain changes, which generally result in changes in the characteristics of the final product, are common to the final moisture.
2. When handling some special materials, the dryer may cause significant wear and high maintenance costs. In addition, large drums have many high maintenance aspects and components, good design, and engineering and maintenance, all of which need to be controlled. However, more are appearances than rules, and improve them by doing quick fixes. system.
3. At the same time, because the dryer is rotating at high speed, the insulation often costs a certain amount of time. At the same time, the true effective length of the insulation, due to the rapid drop of temperature, does not reduce the thermal efficiency of the insulation system, and the high loss is related to the casing. Volumetric machines require a large amount of floor space.
Vacuum dryer manufacturers introduce and if other technologies are adopted, materials can produce a wide range of changes, which will provide the same benefits of high capacity, they are relatively low cost, and when the machine is effective, it can be applied correctly through specific operations.
