Objective:
To understand the general criteria for packing machines for solid foods.
![Page 3: packing equipments for solid foods](https://reader035.fdocuments.in/reader035/viewer/2022081414/54b1ddac4a795933108b45bc/html5/thumbnails/3.jpg)
Introduction:
Foods are being classified into three types, based on their nature.
Solid food Liquid food Semi liquid food
Designing of packing equipments varies for different types of foods.
This is based on the viscosity, temperature, particle size, and foam characteristics.

Factors to be considered:
The packing machine. Conveyors. The deposit and filler systems. Gas medium. Environment of the packing process,
cleaning, and the operators in charge of handling ingredients and food products.

Packing Process:
Product positioning:The product to be packed is first
oriented and then loaded. Product loading:
using a conveyor belt.manually.By pick and place.
Tray and pouch feeding:Providing the tray or pouch

Packaging:Thermoforming and sealing.Tray sealing.Flow wrapping.Form fill seal.
Thermoforming and sealing:The trays are produced in the packaging
machine by thermoforming of a film.

1. Packaging material for the base web is unwound from the reel.
2. The film is heated in the forming die and formed into pockets.
3. The formed pockets are loaded with product.
4. Product.
5. The top web of packaging material covers the filled pockets.
6. The air is evacuated from the sealing die and protective gas is added. Then the pack is sealed.
7. The web of packs is cut across the machine direction initially.
8. Production of the individual packs is completed after the longitudinal cutting operation.

Tray sealing:
The trays are supplied by a belt to a product assembly area for loading, followed by a sealing process.

Flow wrapping:
The product is supplied on a belt to a film-shaping device and tube shape is formed.
Then the tube is sealed in transversal direction and the packs are separated.

Formfill seal:
The product is dropped into a pre-formed vertical tube that is created by sealing a web in longitudinal direction.
After landing in the tube the pack is sealed and separated

Packing machine requirements: The equipment must be easy to
clean and protect the products from contamination and must prevent the ingress of microorganisms.
Separation between product contact and non-product contact areas prevents cross-contamination during operations.
Product contact surfaces are made to prevent build-up of product residue during operations.
