Abstract: A vacuum transfer apparatus and process with weighing controls. An exemplary vacuum transfer apparatus includes a hopper that retains food product and includes a discharge port. A vacuum chamber has an inlet coupled to the discharge port of the hopper, and a member that is time-controlled to dispense product from the vacuum chamber. A portioning hopper receives product from the vacuum chamber and dispenses a predetermined weight of product.

Abstract: An apparatus for vacuum transferring food product having a hopper for retaining food product, the hopper including a discharge port; a vacuum chamber having an inlet and an outlet, wherein the inlet is coupled to the hopper at the hopper's discharge port; a vacuum source for inducing a vacuum pressure between the hopper and the vacuum chamber so as to cause food product retained by the hopper to be drawn into the vacuum chamber though the inlet; a first timing circuit for controlling the length of time that the vacuum pressure is to be applied between the hopper and the vacuum chamber; and a second timing circuit for controlling the rate at which the food product is dispensed from the outlet. The first timing circuit may be adjusted to increase or decrease the length of time that the vacuum pressure is drawn though the apparatus, and the second timing circuit may be adjusted to increase or decrease the frequency of the opening of the outlet.

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.
