Food factory clean workshop clean transfer window instructions

September 07, 2023

According to the “Code for Design of Clean Plants”, the walls and ceilings of the clean workshops of food factories must be constructed with materials that are not dust-producing or smooth. Clean plant design, according to the requirements of the specification, design a return air system.
Clean transfer window features
1. The box body is made of high-quality cold-rolled steel plate and the surface is electrostatically sprayed (or made of stainless steel).
2, the working area cavity is made of sanded stainless steel plate, smooth and smooth.
3. The mechanical interlocking of the two sides of the door ensures that the doors on both sides cannot be opened at the same time.
4, optional accessories are: all stainless steel, roller, UV germicidal lamp, walkie-talkie, electronic interlock.
The indoor air is pressed into the static pressure through the return air plate, and then extruded through a high-efficiency air filter to enter the working area at a uniform cross-sectional wind speed. The dust in the work area is blown out to form a high-clean working environment in the work area.
How to use the clean delivery window of the food factory clean workshop :
1. The transfer window must be mounted horizontally on the partition wall.
2. The grounding terminal on the power socket is connected to the transmission window. It must be reliably grounded during installation to ensure personal safety.
3. The two doors of the transfer window are placed in the closed state. The 220V power supply is turned on, and the main switch on the transfer window is pressed. The indicator light on the switch is on, indicating that the transfer window is in the working state.
4. When the door is opened on either side, the door on the other side is automatically interlocked and cannot be opened, and the opposite indicator light is on.
5. The transfer window with the germicidal lamp can be operated according to the light switch. Before the germicidal lamp is turned on, the two sides of the door must be closed at the same time to be used, but it is strictly forbidden to open the germicidal lamp for sterilization when the user uses the operation, otherwise the eyes and skin of the person may be harmed.
6. In order to reduce pollution, the transfer door is only opened when the item is delivered. The end of the transfer needs to be closed immediately to ensure the normal work of the other side.
7. This equipment should be used in an environment with a cleanliness of not less than 10,000.
8. The clean delivery window of the clean workshop of the food factory should be tested for cleanliness and colony number before use. When it is confirmed that the two indicators meet the technical parameters, they can be used.

Urinalysis Reagent Strip

1. urine analysis strip is dry chemical reaction principle, the human body in the urine of white blood cells, proteins, ph, urine specific gravity, ketone body, bilirubin, occult blood, nitrite, uric bravery, glucose, creatinine, vitamin C, calcium within ten three indexes such as qualitative and semi-quantitative detection.

2. For the use of this product, we must pay attention to several points. For example, at the beginning, we should immerse all the reagent part on the urine analysis strip into the sample, and then take it out immediately.

3. Additionally, the edge of the urine analysis strip should be gently brushed along the mouth wall of the sample container to remove excess urine. Then place the reagent block on the urinalysis strip horizontally up and compare with the color map to record the results.

Rational use of urine analysis strip has played a very good role in our timely detection of disease and timely treatment

[Test Principle]

Urobilinogen:Urobilinogen with diazonium salt produce red violet dyes in strong acid medium.

Bilirubin:The direct bilirubin with dichlorobenzene diazonium produce azo dyes in acid medium.

Ketone:The acetoacetic acid and sodium nitroprusside cause reaction in alkaline medium,which produces red violet compound.

Blood:Hemoglobin acts as peroxidase. It can cause peroxidase release neo-ecotypes oxide (O).(O) oxidizes the indicator and make the color change subsequently.

Protein:It is based on a specific pH indicator attracted by cation on protein molecule,the indicator further ionized and make the color change.This phenomenon is called protein-error-of -indicator principle.

Nitrite:Nitrite and aromatic amine are diazotized to form a diazonium compound.The diazonium compound reacts with tetrahydrobenzo(h)quinolin 3-phenol produce the red azo dye.

Leukocyte:Pyrrole amino acid ester produce free phenol under the hydrolysis of esterase in neutrophile granulocyte,the free phenol couple with phenyl diazonium salt produce purple azo dyes.

Glucose:The glucose oxidized by glucose oxidase catalyzes the formation of glucuronic acid and peroxide hydrogen.Peroxide hydrogen releases neo-ecotypes oxide(O)under the function of peroxidase.(O)oxidizes tetramethyl benzidine, which make the color change.

Specific Gravity:Methyl vinyl ether and maleic acid copolymer is weak acid (-COOH) exchanger,the M+ cation (the major is Na+) in urine reacts with the exchanger and release hydrogen ion,hydrogen ion reacts with indicator produce color change.

pH:The method of pH indicator is applied.

Ascorbic Acid:Ascorbic acid deoxidizes the 2.6-dichlorphenolindophenol dye into colorless in alkaline medium.

Microalbumin:Sulfone phthalein dye has high sensitivity to microalbumin by the method of protein error.

Creatinine:Creatinine with 3,5-Dinitrobenoic acid produce violet compound in alkaline medium.

Calcium:Calcium ion reacts with methyl bromothymol blue produce color change in alkaline medium.
