  • This invention relates to an improving product weighing feature that includes a sensing means for sensing product entering a vacuum chamber and at least one strain gauge load cells on a hopper for determining product weight in the hopper.
  • the prior patent of the Applicant's assignee, No. 6,413,020 describes an apparatus for vacuum transferring food product, such as chicken, that comprises a hopper for retaining food product and having a discharge port; a vacuum chamber having an inlet and an outlet, the inlet of the vacuum chamber being connected to receive product from
  • a first electrical timing circuit controlled the opening and closing of the vacuum source so that transport of the food product is drawn into a vacuum chamber from the hopper upon activation of the vacuum source and opening and closing of the vacuum chamber.
  • a second electrical timing circuit controlled the time 0 during of the vacuum pressure so that metered amounts of the food product may be transported. Additional details of the prior art embodiment from the Applicant are found in the '020 patent.
  • the improved system reduce a likelihood that the food product, 5 such as marinating and/or marinated chicken, would lose moisture during the vacuum transfer and weighing processing, and thus dry out from exposure to atmospheric conditions. It was also of interest to automate a control for the ingress of product from a hopper to a vacuum chamber and for controlling an amount of product added to a portioning hopper receiving product from the vacuum transfer.
  • the invention of the '020 patent was modified to include an improved product weighing arrangement that including an electronic sensor for sensing, and thus controlling, by time of opening of a gate on the processing line to the vacuum chamber, a volume of food product, e.g. chicken fillets, accumulating in a portioning hopper. 15 Additional details are noted in the discussion of the operation of the invention.
  • Another feature of the invention relates to a use of data provided by electronic, strain gauge type load cells mounted to the portioning hopper in combination with product-transferring paddle to control the quantity of food product, e.g. chicken fillets, accumulated in the portioning hopper.

This dwell is adjusted automatically based on data provided by electronic load cells 76a and 76b mounted to the portioning hopper 75.
  • T2 automatically adjusts frequency of cycles to permit an increase or decrease in the volume of chicken filets accumulating in the portioning hopper 75.
  • the quantity of chicken filets drawn into the flexible hose 14 during a given cycle is fixed and controlled by an electronic level sensing probe 77.

  • Tl automatically adjusts to discharge a pre-set, and adjustable, quantity of chicken filets according to the weight of chicken fillets in the hopper 75.
  • strain gauge load cells are provided to determine the product weight in the hopper 75 to provide data for portioning output from the hopper 75.
  • the paddle wheel 78 will turn faster to deliver more chicken filets to the processing line or turn slower to deliver less chicken filets to the processing line.
  • an optimum speed is established for a driving motor for the paddle wheel that is responsive to the load cells, so that more or fewer chicken fillets are delivered according to the driving speed of the paddle wheel 78.

Abstract

L'invention porte sur un appareil et un procédé qui permettent le transfert par le vide d'un produit alimentaire. Une trémie (12) munie d'un orifice de décharge retient le produit alimentaire. Au moins une chambre à vide (16) comporte une entrée et une sortie, l'entrée étant couplée à l'orifice de décharge et la sortie comprenant un élément qui, sur une commande basée sur le temps, libère un produit de la chambre à vide. Une trémie de fractionnement (75) reçoit le produit en provenance de la chambre à vide et distribue un poids prédéterminé du produit.
