Baked Products Are Moldy (Is The Flow Of People And Logistics Design Reasonable?)

4. Only equipment, facilities and material storage rooms related to production are set up in the production area.
(1) Compressors, steel cylinders, vacuum pumps, dust removal equipment, dehumidification equipment, exhaust fans and other public auxiliary facilities for compressed gas should be arranged in the general production area as long as the process requirements permit.
(2) The production area cannot store sundries such as curtains, mops, and outsourcing materials. Anything that has nothing to do with production is clear to the workshop, especially the inner compartment.
(3) In order to effectively prevent cross-contamination of allergens between foods, different allergen foods cannot be produced and processed simultaneously in the same area.

5. It is better to separate the elevators for transporting materials in multi-storey factories.
(1) Because elevators and hoistways are a big source of pollution, and the air in elevators and hoistways is difficult to purify.
(2) If due to the special requirements of the process flow or the limitation of the plant structure, the process equipment needs to be arranged three-dimensionally, and the materials are to be transported by elevator from top to bottom or from bottom to top in the clean room, there should be a space between the elevator and the clean clean area. Airlock or design other measures to ensure air cleanliness in the production area.
In actual production, what are the outstanding problems in the flow of people and logistics design?
1. In fact, it is difficult to design a passage that only transports goods without leaving people.
Judging from the current level of domestic food companies, it is impossible for the production to reach the level of fully enclosed, fully mechanized, and fully pipelined transportation, and the transportation of materials cannot be separated from the level of human handling. The transportation and delivery of a large amount of raw and auxiliary materials, semi-finished products, and inner packaging materials is done manually, that is, people take the materials away.
2. It is not necessary for each workshop to have its own dedicated channel
Generally speaking, in terms of warehouses in production areas, the temperature, humidity and dust in the air should also be effectively controlled. The more doors open to the outside world, the greater the possibility of being polluted by the external environment and entering by insects and small animals. Generally, the medicines or inner packaging materials in the production area are packaged and have obvious signs. Under normal circumstances, there will be no pollution between people and objects, so there is no need to set up their own dedicated channels.
3. The flow of people and logistics is not limited to the hardware setting two channels, the real meaning of reproduction process flow to avoid cross.
"Separation of people flow and logistics" and "avoidance of people flow and logistics crossing" do not formally set up two independent channels with no intersections, but require corresponding measures in the process layout design to avoid people to materials and external environment Cross contamination between materials and materials. As for the statement that "the flow of people and materials cannot be crossed" can only be regarded as a misunderstanding of "the flow of people and materials cannot be cross-contaminated".
