ส�ำคัญทั้งหมด expensive cleaning needs, eventually.
To select proper fitting connectors for food and beverage production lines, following
factors should be concerned:
Material: Fitting material for food and beverage lines should not cause
contamination, or become corrosive. It should be easily washed and cleaned. Stainless
304, 316 or 316L (L for Low carbon) are mostly used to produce food grade fitting.
However, pricing of stainless 304, 316 or 316L (L for Low carbon) fitting connector
are likely more expensive that regular fitting connectors. Again, one of the popular
issues found when selecting fitting connectors is that many users do not know how
to select or match the proper fitting connector material to each objective
Design: Design of food grade fitting should have easy access for sanitary, avoid
gap which might cause microbial collection, and be easy to clean. Food fitting design
should not be threaded.
Roughness: Surface of fitting is very important for food and beverage industry
because smooth surface is easily cleaned, and decreasing chance of contamination.
According to 3A (Triple A) standard, US sanitary standard for machine and equipment
for food and daily product, roughness (Ra) of food fitting must not more than 32 μ-in
and less than 20 μ-in for medical grade (for injected medicine or vaccine).
Crimping Standard: Mostly in Thailand, we can do hose crimping in any hydraulic
shops, which have high risk of contamination either from oil, dust, smoke or bugs.
To prevent leakage, loosing, or tear of hose and fitting, we need to have high standard
and high quality control process which is also difficult. We need to consider many
factors such as hose condition, fitting part for crimping, or crimping method, crimping
force, etc., Also appearances are as important as quality nowaday.
The most important thing for food and beverage manufacturer is to provide the
best and safe product to customer, so manufacturer should be assured that material
and tools used in production lines are in working condition and safe to both workers
and products.
