Posted by sytopstellitealloy on Jan 2, 2019 in Allgemeines
Shenyang Top New Material Co.,Ltd, Started in 2001, we have almost 20 years producing experience for over 500 kinds of products and 10 years exporting experience served satisfied customers in over 50 countries.

As we all know, Stellite Alloy is a hard alloy that is resistant to all types of wear and corrosion and high temperature oxidation. Known as the cobalt-chromium-tungsten (molybdenum) alloy or the cobalt-based alloy .Stellite alloy is a kind of alloy containing cobalt as a main component, containing a considerable amount of nickel, chromium, tungsten .

There are many models of Stellite alloys. Such as Stellite 3,Stellite4,Stellite6,Stellite12,Stellite20 and so on.

Among them ,stellite 6 is one kind of the most widely used cobalt-based alloy with good overall performance. It has excellent resistance to a wide range of mechanical and chemical degradation over a wide temperature range and maintains reasonable hardness up to 800 ° C (1470 ° F). Special properties are its excellent self-assembling anti-wear properties (resulting in its wide use as a seat material), its high temperature hardness, and its high impact and cavitation corrosion resistance.

This Stellite Alloy 12 is ideal for a variety of surface hardening processes. It has a lower tendency to crack than Stellite 12 in multiple layers, but is more resistant to wear and metal to metal or wear conditions. It can be rotated with a carbide tool. Stellite 6 is used for seat and gate; pump shaft and bearing, anti-corrosion cover and rolling coupling. It is often used for self-coordination.

Mini Dairy Plant Produces Healthy And Guaranteed Products

There are many options when buying milk at the supermarket. Two important types of milk are fresh milk, which has a short shelf life, needs to be stored in the refrigerator, and has a long shelf life of milk that can be stored at room temperature. Different countries like different types of milk. Why is this difference? Does the type of milk have an effect on its quality and nutritional value?

The main difference between these milks is the temperature used during processing. For fresh milk, use mild pasteurization at a temperature of about 72 °C. In this way, the pathogen is killed and the product is safe to eat. However, bacteria that destroy milk will not be killed, so it is necessary to store the milk in the refrigerator. In order to extend the shelf life, it is usually treated with ultra-high temperature (UHT Milk Machine), which is very high temperature (130 - 140 °C) for a few seconds. This treatment kills all bacteria that can cause spoilage. This milk has a long shelf life and can be stored at room temperature because bacteria no longer destroy the product. The advantage of UHT milk is that it does not require refrigerated transport/storage, making it easier for dairy companies and retailers to collaborate.

But why don’t we just disinfect all the milk if it makes life easier? This is mainly because of the taste. Pasteurization has a very limited effect on taste compared to raw milk. On the other hand, UHT sterilization results in the formation of a specific flavor due to the high temperature used.

So what about nutritional value? The main nutrients (protein, fat, lactose, minerals) in milk are not damaged by ultra-high temperature sterilization, keeping them intact. For some vitamins, a small reduction (up to 10%) may occur. Therefore, the nutritional quality is basically the same. Only when the sterilization is more intense, this can be seen in brown, and the nutritional value is reduced due to the destruction of the protein (essential amino acids).

All in all, the main difference between fresh milk and ultra-high temperature milk is the taste and shelf life, and these products are almost the same in nutrition. Therefore, more and more Mini Dairy Plant choose uht technology and machines. After all, consumers nowadays are more fond of healthy and guaranteed products.
