As the most commonly used mechanical equipment for meat processing enterprises, the main function is to roll the processed meat such as beef, lamb, chicken, pork, fish and so on in the vacuum state, which can not only improve the speed of seasoning into the meat, and maximize the moisture in the meat, but also achieve the purpose of fresh and tender meat and high yield. The following is the working principle of the vacuum roller kneading machine, operating instructions, use methods, selection points, maintenance and other knowledge.
Working principle of vacuum roller kneading machine
Vacuum roller kneading machine is in the vacuum state, the use of the principle of physical impact, so that the meat in the roller up and down, impact each other, beating, to achieve the effect of pickling, so that the meat evenly absorb pickling, improve the strength of the meat and the elasticity of the product, through rolling can make the flesh protein decomposed into water-soluble protein, easy to be absorbed by the human body, At the same time, the additive material (starch, etc.) can be integrated with the flesh protein to achieve tender meat, good taste, and high export rate. The machine has the function of lung respiration, allowing the product to expand in the roller, reducing the reciprocating movement, improving the structure of the meat tissue, and improving the cutting effect.
Vacuum roller kneading machine operation instructions
1. The vacuum roller kneading machine is to tenderize meat, fully absorb salt water, and extract protein through the circular movement of tilting roll kneading (massage) in the vacuum state, which is conducive to increasing the water retention of meat.
2. Before vacuum kneading, the meat should be injected with salt water.
3. First check whether the machine can operate normally and the vacuum device can work normally. If the machine is in good condition, clean the inner cavity of the vacuum roller kneading machine and dry the surface.
4. Put the meat for rolling, close the lid, vacuum, plug in the power supply for rolling and rolling, and start to work.
5. Vacuum rolling should be carried out in intermittent mode, and the rolling time should be carried out according to the requirements of processed products. In the rolling process, the temperature should be prevented from being too high, otherwise, protein denature will be caused and meat quality will be affected. After the rolling operation is completed, the vacuum should be released, the lid should be opened, the meat should be removed and the inner cavity should be cleaned.
The best use of vacuum rolling machine tips:
1. The load of the rolling kneading machine: when the rolling kneading machine is rotating, if the amount of meat in the cylinder is too much, the rotation will be greatly affected, and the mixing will be uneven, if the amount of meat in the barrel is too little, it will lead to excessive rolling and kneading, resulting in damage to the meat quality, and the consumption cost will increase. It is recommended that about 60% of the full cylinder load, floating between 5% under the roller kneading machine, depending on the density of meat.
2. Rolling and kneading interval time: In the rolling and kneading production process, continuous rolling and kneading is unnecessary and laborious. It is usually recommended to knead for 20 minutes and rest for 5-10 minutes.
3. Rolling time: The total rolling time is very important for the uniformity and standardization of the product. Once a procedure has been adopted that can produce a standardized product, the procedure, or rolling cycle, should remain unchanged.
4. Temperature control: Some experts believe that you can get better cured meat color in warmer environments. However, considering the shelf life, safety and yield of the product, it is best to roll at 2-4 ° C, when the product is rolled at 8 ° C or higher temperature, the binding force and yield of the product will decrease significantly, but the quality should be put first.
5. Vacuum: Vacuum plays an important role in the roller kneading machine, and the vacuum can ensure that the brine quickly penetrates into the meat and helps to remove the bubbles in the meat.
The vacuum expands the meat to achieve a certain tenderness. The vacuum in the cylinder is usually drawn to 70 to 80 percent of an atmosphere. However, too high a vacuum has the opposite effect, because the moisture in the meat is drawn out at a high vacuum.
6. Kneading direction: The kneading machine should gently push, massage, lift, curl and drop the meat to achieve the best results. The equipment should have a reverse function, and the last 5 minutes of the rolling cycle before unloading should be reversed to clean out the meat and protein on the back of the drum fins.
Vacuum roller kneading machine select the key points
1, the choice of model: the key is the choice of model, there are too many rolling models on the market, the same model price and output are not the same, the buyer how to choose?
The first choice is to determine the output you need (the required loading amount each time), and to determine the loading requirements of the order on the contract, for example, the effective loading volume of the 300L vacuum roller kneading machine is generally about 112kg, that is, it can be loaded with about 100 kg, so that there is room to add curing water.
2, the choice of configuration: most production enterprises in the customer has no special requirements to choose stainless steel 201 production, which does not meet the food hygiene standards, so the part in contact with food must be made of food-grade SUS304 stainless steel.
3, the choice of frequency conversion device: the use of a variety of products and large vacuum roller kneading machine must use frequency conversion device, and part of the single product and the need for a small vacuum roller kneading machine model can not use frequency conversion device, the role of the frequency conversion device is to adjust the rotation speed of the vacuum roller kneading machine, and one point is that the use of frequency conversion control equipment motor long service life.
Vacuum rolling machine repair and maintenance:
The vacuum roller kneading machine has a simple structure, mainly including the frame, drum, reducer, vacuum pump, chain drive, control appliances and other parts of the composition, from the structure of the equipment can be seen that the vacuum roller kneading machine maintenance mainly refers to the reducer and vacuum pump, reducer and vacuum pump warranty time is generally one year, one year can be unconditionally replaced, if more than one year, Can negotiate with the vacuum roller kneading machine manufacturer repair or replacement. You can also buy it yourself and install it.
1. After the work of each vacuum roller kneading machine, open the bottom valve switch of the vacuum oil-water separator, drain the water, remove the vacuum suction, clean the oil-water separator of the vacuum pump, and ensure that the vacuum pipeline is smooth.
2, the vacuum pump should stop the pump once a month to check the pollution of the oil, if the oil in the vacuum pump has been contaminated, the oil should be changed in time. Before oil change, the pump must be no-load forward for 15 minutes, let the oil heat, stop the pump and open the oil plug to drain the dirty oil, clean with some new oil or inject new oil after oil cleaning the pump.
3, often check the reducer oil level, such as found that the oil level is lower than the oil window height 1/2 should be filled in time 30 mechanical oil.
4, the vacuum roller machine electrical control box should be firmly grounded to ensure the safety of electricity.
As long as the daily attention to maintenance and maintenance, not only can reduce the failure rate, improve the work efficiency, the maintenance rate of the vacuum roller kneading machine is basically zero.
The above is about the working principle of the vacuum roller kneading machine, operating instructions, use methods, selection points, maintenance and maintenance of the introduction, the most popular automatic vacuum roller kneading machine on the market in addition to the characteristics of vacuum breathing roller kneading machine, but also has frequency conversion technology function, so that the number of roller kneading revolution according to the process arbitrary adjustment, making the machine safer, more convenient, more energy-saving and efficient. The machine is made of stainless steel, compact structure, both ends of the drum are using spinning type cap structure, the greatest increase in the tumble space in the drum, so that the effect of rolling products is uniform, low noise, reliable performance, and higher efficiency.
