The food factory project must use a filtered air system for ventilation. In this system, the outside air is pumped after being filtered and, if necessary, heated or cooled through the side channels inside. This system causes the air inside the factory to come out of the doors and prevent dust and insects from entering. The power of these devices must be such that they can change the air inside the factory every 25 minutes. The use of ceiling fans is not recommended in these places, except in exceptional cases when the volume of steam inside is so high that normal ventilation can not take it out. Compared to the activity of a factory with the above characteristics, step-down workshops with non-standard facilities and maximum pollution, offer seemingly chic products to the market that in terms of quality and hygiene are far from inspection and control by agents. The consumer must be aware of the details of standard production, and the producer of standard products also has a duty to inform the details of his work for consumer awareness so that both the difference between standard production and counterfeiting can be seen and investing in this field is unpaid. نماند
