Judging method of counterfeit flat frying tea machine

In recent years, with the development of the tea industry in our province, the market demand for flat-shaped tea frying machines suitable for the majority of rural households is very large, coupled with the low technical content, easy imitation, and small investment in production. The manufacturing cost is low, so the workshop-type individual production enterprise came into being. According to incomplete statistics, there are nearly one hundred such production enterprises in the main tea producing areas of Zhejiang Province. The vast majority of these enterprises are private and small individual enterprises. The scale of production is small, ranging from a dozen to a few, and as few as three to five. The vast majority of workers are local farmers. The production equipment is old and broken. Some of them have only one electric welding machine. They are all hand-made by workers. The annual output is more than 100 sets, and the minimum is also 20 or 30 sets. Most of these companies do not have product drawings, mainly relying on workers to copy samples, hand-knocking, and workshop-style production. The quality awareness of workers is poor. Most enterprises do not organize production according to standards. Even most enterprises do not know that there are standards for producing such products. The phenomenon of non-standard production is serious, resulting in a lot of counterfeit and shoddy products on the market, and the quality is uneven. The safe production guarantee, efficiency increase and income increase of tea farmers have brought certain impacts.

The production enterprises of flat tea frying machine are mainly distributed in the main tea producing areas of Zhejiang Province, such as Chun'an County, Xinchang County, Zhangzhou City, Fuyang County and Chun'an County. The products produced by these companies are similar in structure, and most companies copy other people's products. In the production process, the process is simplified, the workmanship is reduced, the shoddy is made, the safety design and manufacture are congenitally insufficient, and the product quality is inferior. For example, in the quality supervision and spot check of Cangzhou City in 2005, 20 batches of products were randomly selected, and the pass rate was only 5%. After spot checks and investigations, the main quality problem of counterfeit and inferior flat tea frying machine is that the fry materials use aluminum alloy and contact tea. Painted parts, rotating parts, no guards and dangerous parts without safety warning signs.

These inferior products have had many vicious wounding incidents. For example, in 2004, according to incomplete statistics, there were more than 80 incidents of burns and injuries. In the beginning of 2005, more than 200 incidents of burns and crushing occurred in the province, which became the focus of attention of the whole society and relevant departments. Through the quality supervision and management of the agricultural machinery department in the past two years, most of the safety hazards have been eliminated, and the quality of products has been improved. However, a large part of the “switch” (referring to stop production during supervision activities and production after supervision) is still full of tea. Machine market.

The expression of fake and shoddy flat tea frying machine

Through the investigation and testing of the flat-shaped tea frying machine sold in the market, the main manifestations of the fake and shoddy flat-shaped tea frying machine are as follows:

1, "three no" products

The product has no factory name, no factory address, no product certification. As the flat tea frying machine manufacturer has a part of individual small businesses. Some are even small-scale productions such as husband-and-wife shops, father-child stores, etc., and all of them are produced irregularly according to the agricultural season, and there is no registration for the industrial and commercial department. Therefore, the basic information of any trademark, factory name, factory address and other products cannot be seen on the flat tea frying machine produced by it.

2, the product does not meet the safety requirements

1 product design is unreasonable, there are potential safety hazards that endanger personal health;

2 Exposed rotating parts (such as pulleys) have no safety guards or protection is not in place;

3 In the dangerous parts that are likely to cause personal injury, the safety warning signs are not marked as required;

4 Electrical equipment such as motors are not protected against leakage or protection is not in place.

3. The product does not meet the food hygiene requirements

1 fried hands are made of aluminum alloy building materials;

2 paint inside and outside the pot and the contact area of ​​the tea;

3 The inner filling of the pressure plate is something like black heart cotton.

4. False propaganda

The production capacity and supporting power indicated in the manual do not match the actual conditions.

5, cut corners

1 Reduce the specifications of the material. The thickness of the whole thin steel plate is less than 1.2mm, and even some parts are made of scrap steel plate or three plywood as the whole machine protective plate; the motor or temperature control table uses second-hand goods.

2 Reduce the post-processing steps of components. The burrs and acute angles on the surface of the parts are not processed.

3 reduce the painting process. The surface of the whole machine has no primer, uneven paint, and there are paint leakage and paint stripping.

Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within living organisms, including DNA replication, catalyzing metabolic reactions, responding to stimuli, and transporting molecules from one location to another.


We supply protein, which is generally consumed immediately before and after exercising, or in place of a meal. Some types of protein are to be taken directly before and after a workout, while others are to be taken before going to bed. The theory behind this supplementation is that bodybuilders, by virtue of their unique training methods and end-goals, require higher-than-average quantities of protein to support maximal muscle growth.
