Environment 4:
The Main Corridor:
A Highway for Substrate &
Product Flow
Purposes: A central hallway connecting the
essential environments to one another, facilitat-

ing movement of materials, products and

Facility: Often times, a metal framed, open
truss building, is centrally located, broadside to
the growing rooms. Ceilings should be at least
12 ft., ideally 20 ft. high. Here again, wood sur-

faces should be minimized. Floors should be
cement with drains and have access to water
lines for maintenance and clean-up.
Maximum Temperature: Ambient
Minimum Temperature: Ambient

Humidity: Ambient: 20-80% rH
Light: Skylights or moisture proof fluorescents

Insulation: None needed.
Positive Pressurization: Not needed.
Additional Comments. Since this is a high traffic area, two-way passing is essential. Those
using forklifts must have ample turn-around
space for maximum mobility. Many cultivators
have charts andlor remote temperature sensors

constructed into the walls by each growing

room. Bug-traps are placed at several locations
to intercept winged intruders before possible
entry into the mushroom growing rooms.

Environment 5:
Sorting, Grading &
Packing Room
Purpose: To sort, grade, and package mush-

rooms into their end-user containers.
Facility: A well lighted room with gravity conveyors, sorting tables, and often a blast-chiller
which quickly cools the mushrooms prior to
packaging and storage in the refrigeration
room. This room is usually located at the end
of the main corridor and is immediately adjacent to the refrigeration and shipping rooms.
Maximum Temperature: 50° F. (10° C.)
35° F. (1-2° C.)

Humidity: 50-75% rH
Light: 500-1000 lux.

I have seen a number of

configurations of this type of processing room.
Mushrooms usually arrive in open-grate plastic carrier baskets. The baskets are placed into

the airstream from the blast chiller (or in the
cold room) awaiting sorting into cardboard,
end-user boxes. Although this room is kept
cool, the packaging personnel are comfortable
at this temperature, busily, sorting, weighing,
labelling, and arranging boxes for distribution.

Environment 6:
The Refrigeration Room
Purposes: To chill mushrooms to 35 ° F. (1-2°
C.) so they can be maximally preserved.
Facility: A standard refrigeration room.
Maximum Temperature: 38° F. (3° C.)
Minimum Temperature: 32° F. (0° C.)

Humidity: 60-80% rH.

Light: Only as needed for personnel.

Insulation: R30-R60.
Positive Pressurization: No.
Additional Comments: Installers should engi-
