What are the precautions for the installation of purification workshop transmission window in food processing?

Purification workshop Transmission Window for Food Processing-Precautions for Installation (whole process, can be directly used for construction and acceptance)

The following is a must-see installation point for SC/purification certification of food factory, covering location, wall, sealing, electrical, safety and acceptance, without stepping on the pit.

A, installation location selection matters needing attention

Installed between clean area and non-clean area

Such as: general area → clean packaging room, cooling room → inner room.

It is forbidden to install it in the middle of the pedestrian passage to avoid interfering with production.

Avoid air ducts, water pipes, wires and beams.

Play the line in advance to ensure that there is no pipeline in the hole.

Height should conform to ergonomics.

Height of the bottom of the transfer window from the ground: 600 ~ 800 mm.

It is convenient to put baskets and take things, without bending over or tiptoeing.

Stay away from dust, water and high temperature areas.

Keep away from cleaning pool, frying area and steamer to prevent corrosion and rust.

Second, the wall and the hole construction attention

Size of the hole must be 20 ~ 30 mm larger than the frame outside the transmission window.

Easy to adjust the horizontal and vertical, easy to glue and seal.

The wall must be flat and firm.

The purification board wall/red brick wall should be vertical without looseness.

It is forbidden to open on the load-bearing structure, main girder and main column.

The mouth of the cave must be reinforced.

Reinforcing ribs/edge strips should be added to the purification board wall to prevent later deformation.

Third, pay attention to equipment installation and positioning

Must be horizontal and vertical.

Calibrate with a level, without inclination or skew.

Tilting will lead to: automatic door opening and closing, lax sealing and interlock failure.

The gap between the box and the wall is even.

The left, right and up gaps are controlled at 10 ~ 15mm.

Double doors must be oriented correctly.

One side is in the unclean area, and the other side is in the clean area. You can't install it backwards.

Ensure that the interlocking mechanism is normal.

Post-installation test: one door is open and the other door is locked.

Four, sealing and leak-proof key (food workshop)

All gaps must use food-grade sealant (neutral silicone/PU sealant).

Inside and outside are completely sealed, with no gaps and trachoma.

The sealing strip must be intact and undamaged.

After the door is closed, it fits completely and does not leak light.

It is forbidden to use ordinary glass glue.

Must use mildew-proof, food-grade and easy-to-clean glue.

Make a small arc or edge at the bottom.

No dust and water accumulation, easy to clean.

Five, electrical and ultraviolet lamp installation

Separate wiring of power supply: 220V/10A.

Wires shall be jacketed, without exposure and moisture.

The ultraviolet germicidal lamp is installed at the top.

It is not blocked by objects, and there is no dead angle in irradiation.

Must be equipped with gating linkage/timing switch.

The door opens → the lights go out; Door closed → sterilization can be started.

The switch is installed on the outside for easy operation.

It is forbidden to install in a clean area to avoid pollution.

Six, door, interlock, hinge debugging

The two switches are smooth, free from jamming and abnormal sound.

The interlock function must be 100% effective.

This is the key item of SC certification.

No light leakage or air leakage after the door is closed.

Hinge/hinge is firmly fixed and not loose.

Seven, food workshop unique sanitary installation requirements

The transfer window must be made of 304 stainless steel.

Corrosion-resistant, easy to clean and rust-free.

The inner and outer surfaces are smooth, free from dead corners and burrs.

It is forbidden to have exposed screws and dust in grooves.

After installation, it must be thoroughly cleaned and disinfected.

Remove glue marks, dust and oil stains before putting into use.

Eight, safety precautions

It is forbidden to pile up articles above the transfer window.

It is forbidden to slam or kick the door.

Do not look directly at the ultraviolet lamp when working, and do not open the door.

Check the sealing, interlocking and ultraviolet function regularly.

Nine, installation acceptance (in a word)

Location compliance

Horizontal vertical

Tightly sealed and dust-tight.

Double door interlock is normal.

Ultraviolet sterilization is effective

The surface is smooth and easy to clean

→ If the above requirements are met, the SC/food purification audit will pass directly.
