A . CASING SOIL PREPARATION

 
 
Casing soil stimulates mushrooms mycelium to pin and form mushroom on its surface. This soil has to be of a nature which can hold water and also support mushrooms.
 
  CANNING PROCESS  
 

To achieve the highest of hygiene standards required for export of food product, an automatic canning line has been provided. The following are the major steps in the process. To obviate damage due to material handling the line has been installed near the growing area.

 
1. PRE-CLEANING
In this process Pre-cleaning vibrators will separate foreign particles, hair and soil from fresh mushroom brought from the growing rooms.
2. WASHING

The mushrooms are cleaned by an injection flotation washing system where air under moderate pressure is blown and under time adjustable process the water circulates through this spraying system.

3. BLANCHING
Blanching is done by continuous belt blancher. During blanching procedure the product is permanently submerged in steam and water avoiding oxidation and discoloration. Temperature is adjusted from +70 0 C to 98 0 C.
4. COOLING

The continuous counter flow cooling system is used chilling the mushroom to 1 0C

5. GRADING
Mushrooms are delivered to the grader through a belt conveyance into drums and driven by timing belts and guide rollers. In this process four grades of blanched mushrooms are graded, depending on their cap size.
6. SLICING

Slicing machine slices the mushrooms, 6mm thick in a parallel shape.

7. PACKAGING/ WEIGHING

The cans are filled with sliced or whole processed mushroom and weighed automatically.

8. BRINING AND EXHAUSTING UNIT

Brine is added to the cans filled with mushrooms and temperature revised to 78 0C – 98 0C, and passed through exhaust box before closing the cans.

9. CAN SEAMING

Semi-automatically the cans and lids are seamed.

10. RETORTING

The seamed cans are put into the retort and heated to 125 0C and then taken out for cooling.

11. LABELLING AND PACKAGING

The cans are labelled/packed into cartons for dispatch. The cans used are A 10 which have drained weight of 1930gms and gross weight of 3200gms and A 2.5 cans having drained weight of 450gms and gross weight of 850gms.
