Medical protective masks are masks made of one or more fabrics that have isolation effects on viral aerosols, virus-containing liquids, and so on. Under the respiratory airflow, it still has a barrier effect on viral aerosols, virus-containing liquids, etc., and when removed, the outer surface of the mask does not contact the human body, can filter particulates in the air, and block droplets, blood, body fluids, secretions, etc. . The use of medical masks includes adhesion testing, training, model selection, medical treatment and maintenance.

First, the process: raw materials → fruit washing → fruit peeling → cleaning → beating pulping → refining → deployment → degassing → sterilization → filling → capping.
Second, processing points:
1. Raw materials: When buying fresh fruits, pay attention to variety and color. Rotten fruit can not be used as a raw material for processing.
2. Wash the fruit: Before the processing, artificially select raw materials, remove colorless kernels and some bad fruits that are already rotten, and rinse them with tap water.
3. Shelling: The pomegranate is peeled open with a stainless steel knife and the shell is removed manually, and the pomegranate seeds are separated from the septum as much as possible.
4. Washing: The peeled pomegranate seeds are immersed in circulating water and rinsed once to remove the crushed skin and the septum. The white grains and the rotten grains are promptly removed. Drain the water and send it to the second washing tank. Rinse with water and rinse with water.
5. Beating and seeding: The pomegranate seeds that drained the water were passed through a scraper conveyor and fed into a double tracker. The mixture was then mixed with an acidulant and beaten to remove seed coats. The first beating is selected with a 1.5mm screen size for beating; the second beating is selected with a 0.5mm screen size for beating. The purpose is to increase the pulping rate and prevent the broken kernels and nuts from the pulping process from entering the pulp and affecting the quality of the finished product.
6. Refining: Using a double-stage colloid mill to grind the beaten slurry. The first rough grinding, the second grinding to a fineness of about 20μm.
7. Dispense: According to the formula, the excipients will be dissolved and then pumped into the mixing cylinder, and then the pomegranate juice will be added to the pure water. Formula: 15 grams of pomegranate pulp juice, compound stabilizer 0.06%-0.08%, compound sweetener (sweetness of sugar 405, Langer's protein sugar sweetness 60%), ethyl maltol 30mg/kg, and the rest are purified water.
8. Vacuum degassing: After the prepared slurry is degassed under a vacuum of not less than 0.07 MPa, it can reduce the gas brought in by the slurry during the beating and refining, and reduce the oxygen and coking in the sterilization process. phenomenon.
9. Sterilization: The degassed material is sterilized by a sterilizing device. The sterilization temperature is 90-105° C. and the time is 50-60 seconds. Then in the sterile room for hot filling, sealing, rapid cooling to room temperature.

Function and composition: The Medical Protective Mask consists of a mask face and a tightening belt. The mask face is divided into three layers: inner, middle and outer. The inner layer is ordinary sanitary gauze or non-woven fabric. Propylene fiber melt-blown material layer, the outer layer is non-woven fabric or ultra-thin polypropylene melt-blown material layer. This high-efficiency medical Protective Mask is highly hydrophobic and breathable, and has a significant filtering effect on tiny virus-carrying aerosols or harmful fine dust, and the overall filtering effect is good.
The medical protective mask has a good fit with the wearer's face, can filter particles in the air, block pollutants such as droplets, blood, body fluids, secretions, etc., and can filter non-oily particles by more than 95% Personal protective equipment commonly used to deal with airborne diseases.
Scope of application: Medical protective masks are better protective products. It is recommended to wear when there is serious environmental pollution or sudden medical infectious diseases (such as respiratory tract infectious diseases), to prevent the spread of viruses from patients or the environment to users.
Product specifications: According to the national standard GB 19083-2003 "Technical Requirements for Medical Protective Masks", important performances of medical protective masks include filtration efficiency, adhesion, liquid barrier performance, comfort, hygiene, and biological safety tests.
Important technical indicators: including non-oily particle filtration efficiency and airflow resistance.
(1) Filtration efficiency: Under the condition of air flow (85 ± 2) L / min, the filtration efficiency of aerodynamic median diameter (0.24 ± 0.06) μm sodium chloride aerosol is not less than 95%.
(2) Tightness: The overall fit factor of the mask should not be less than 100.
How to use: How to wear a head mask
(1) Gently pinch the nose clip and place the mask on the face to ensure that it can cover the nose and mouth.
(2) The upper elastic band is fastened on the head to prevent air from entering.
(3) Tighten the lower elastic band around the neck.
(4) Be sure to fully open the mask to minimize the number of layers used during breathing.
How to wear earhook masks
(1) Pass the ear straps with both hands, place the nose clip on the upper part, and wear the mask on the nose and mouth
(2) The ear strap should be placed at the base of the ear and spread from head to toe, so that the folds of the mask are fully unfolded, which helps to cover the face to the greatest extent and minimize the number of layers required for breathing.
(3) Gently pinch the nose clip to prevent air from entering.
Pomegranate fruit drink
Pomegranate fruit color is gorgeous, sweet and sour, cool. It contains 79% moisture, more than 175 carbohydrates, and is rich in vitamins. It also contains 2.5% crude cellulose and 0.8% ash. Pomegranate is not only available for fresh food but also for processing fruit juices. Here are the processing points.
