Problems solved by technology

[0002] At present, there is usually a certain amount of oxygen in food-grade powder packaging products. Over time, the surface will oxidize in contact with air, destroying the original color, aroma, taste and nutrition of the product, and easily causing moisture absorption, Agglomeration and anti-oil phenomenon lead to deterioration, so its shelf life is relatively short. If you want to extend the high-quality period of the product, you need to filter the oxygen in the product and carry out vacuum nitrogen filling treatment, and you want to filter out the oxygen in the packaged product , the general vacuum tube cannot be realized due to the large caliber, so how to provide a method of vacuum filling food-grade fine powder with nitrogen, and how to obtain the desired product by this method has become a difficult problem in front of people

Embodiment Construction

[0020] Such as figure 1 The nozzle-type vacuum device shown includes a frame 1, a sealing clamp 2 is arranged on the frame 1, a nitrogen filling nozzle 3 and a vacuum nozzle 4 are arranged above the sealing clamp 2, and a filter screen 5 is arranged at the lower end of the vacuum nozzle 4. The pore size is smaller than the diameter of the fine powder.

[0021] The method of the present invention includes the following steps:

[0022] 1. Pack the powdered product into the packaging bag;

[0023] 2. Insert the nitrogen filling nozzle 3 and the vacuum nozzle 4 into the packaging bag;

[0024] 3. Use the vacuum nozzle 4 to vacuum, and then use the nitrogen filling nozzle 3 to fill the bag with nitrogen;

[0025] 4. Repeat step 3 twice and vacuum again;

[0026] 5. Withdraw the nitrogen filling nozzle and vacuum nozzle;

[0027] 6. Seal the bag opening.

[0028] When vacuuming for the first time, suck up the air in the upper part of the packaging bag. When filling nitrogen for the firs...

Abstract

A vacuum nitrogen-filling method for packing the edible superfine powder includes such steps as loading the powder product in package bag, inserting vacuumizing tube and nitrogen gas filling nozzle, vacuumizing, filling nitrogen gas, vaccumizing again, nitrogen gas filling again, removing, said tube and nozzle and sealing the package bag. Its advantages are long storage time and no loss in color, smell, taste and nutrients.

Description

Technical field: [0001] The invention relates to a method for vacuum filling fine powder with nitrogen, and a product obtained by this method. Background technique: [0002] At present, food-grade powdered packaging products usually contain a certain amount of oxygen. Over time, their surface will oxidize when contacted with the air, destroying the original color, aroma, taste and nutrition of the product, and easily cause moisture absorption, Agglomeration and oil reversal phenomenon lead to deterioration, so its shelf life is relatively short. If you want to extend the quality period of the product, you need to filter the oxygen in the product and perform vacuum nitrogen filling treatment, and you want to filter out the oxygen in the packaged product The general vacuum tube cannot be realized due to its large caliber. Therefore, how to provide a method for vacuum nitrogen filling and packaging of food-grade fine powder, and to obtain the required products by this method, has be...
