Abstract
A food product mixer with a pair of door openings in its front panel includes a door mechanism with a pair of slideable doors. Each door is slideable on a pair of sliding rods toward and away from the opening with which it is associated. Means are provided to cause both doors to slide simultaneously on their sliding rods to a closed position in which each door closes its associated opening. The sliding rods on which each door slides are rotatable to separately lock the door when it is in its closed position, as well as to separately unlock it. An unlocked door slides back along its rods, away from the opening, due to food pressure applied theron by food in the mixer, thereby enabling the food to be discharged through the opening. Either door may be unlocked with the other door remaining in the locked position. The rotation of the rods to lock and unlock a door may be achieved manually or by actuated means. The entire door mechanism is covered by a protective enclosure so as to prevent food product, discharged through either or both openings, from being contaminated by matter from structural members located above the openings.
