Small knowledge of commercial kitchen equipment丨The characteristics of food-grade stainless steel and aluminum-magnesium alloy
Commercial kitchen equipment and food machinery are widely used product equipment in catering and related fields. Compared with other equipment, their service life is relatively long and the frequency of use is relatively high. The general design life is 5-10 years. Because it is an indispensable part of the user's daily business process, consumers are generally more cautious when buying, especially when choosing the material of the equipment.
What is aluminum-magnesium alloy? What is the difference between food grade stainless steel and ordinary stainless steel?
Don't worry, let's answer one by one next.
Stainless steel and food grade stainless steel
Stainless steel is the abbreviation of stainless and acid-resistant steel. It is a stainless steel with rare metal components such as chromium and nickel. It is resistant to weak corrosive media such as air, steam, and water. The common types of stainless steel in the catering industry are 304 stainless steel, 201 stainless steel and so on.
Food-grade stainless steel refers to stainless steel that meets the national mandatory standard GB4806.9-2016 "National Food Safety Standard for Food Contact Metal Materials and Products". The country has clear regulations on both raw materials and heavy metal precipitation of raw materials for food-grade stainless steel.
The stainless steel used by our company is mainly divided into ordinary high-quality stainless steel and food-grade stainless steel. Ordinary high-quality stainless steel is mainly used for parts that are not in direct contact with food, such as the fuselage and base; while food-grade stainless steel is mainly used for parts that are in direct contact with objects such as barrels and pots.
The stainless steel meat grinder, stainless steel bone sawing machine, meat bowl chopper and food vegetable shredder produced by our company are all made of ordinary high-quality stainless steel and food-grade stainless steel. The appearance is beautiful, clean and fashionable, the pot body is clean and hygienic, rust-proof and corrosion-resistant, and can work in different temperature kitchens.
When the heavy metal migration of stainless steel products exceeds the limit during long-term use, it may endanger human health. Therefore, when choosing commercial kitchenware, you must choose a strong manufacturer to ensure that the food carrier part of the machine is made of "food grade stainless steel."
Our laboratory (the laboratory is ITS, SGS-certified TMP laboratory) has a RoHS tester, which can detect the composition and content of related metal elements in stainless steel, and every year we entrust a third-party professional testing agency to test the company The instrument is calibrated. According to the company's internal incoming material inspection requirements, each batch of purchased stainless steel must be randomly cut and tested to ensure the quality of the stainless steel.
Aluminum-magnesium alloy
Aluminum-magnesium alloy usually refers to aluminum alloy with magnesium as the main additive element. It has the advantages of high strength, low density, and good heat dissipation. It is widely used in electronics, automobiles, aerospace and other fields. It has many advantages such as high specific strength, low density, corrosion resistance, recyclability, good thermal conductivity, anti-electromagnetic radiation, and thin-wall molding, and is widely accepted by the public.
Generally, the pretreatment of magnesium alloy parts can be divided into four categories: mechanical cleaning, solvent cleaning, lye cleaning, and acid cleaning. These methods can be used alone or in combination.
Although aluminum-magnesium alloys have many advantages, the production process is difficult, and not all manufacturers have the conditions for production. The aluminum-magnesium alloy meat slicers, meat bone saws, and meat grinders produced by our company are well-made. They are polished by robots and all anodized. They are beautiful and stylish, clean and hygienic, resistant to high temperature and corrosion, and have both appearance and strength.
With the development of the food industry, the issue of food hygiene has become more and more important. The importance of food machinery as the part in direct contact with food materials in the food processing process directly determines the safety and sanitation of food. Therefore, in the process of purchasing food machinery, the first thing to consider is that the raw materials used to manufacture the food machinery meet the national food-grade requirements and must not cause any pollution to the food.
In line with the original intention of a catering person, we will never give up the perfect pursuit of product raw materials and details on the road of continuous advancement. Adhere to the use of safe and reliable materials to manufacture products that meet national standards, so that every consumer can rest assured and eat at ease. Only in this way can we be worthy of our reputation of "exporting famous brands and domestic products".
