Definitions

  • the present invention relates to filtration of cooking oil and more particularly relates to a filter for enabling removable of unwanted food and particulate matter from the oil. More particularly the invention relates to a filter tray im nersible in cooling oil and capable of receiving and retaining for removal particulate oil contaminants.
  • a sump is provided below heat tubes which extend through the oil bath. Food is cooked above the heat tubes and dislodged particles accumulate in the sump. The sump area below the heat tubes is at a lower temperature than the cooking bath and disagreeable flavors can develop from the over cooked food particles in the sump. Furthermore, if the sump is drained, filtered, and returned to the cooking bath it will be at a lower temperature than that required for cooking, necessitating reheating the oil before the cooking procedure can be repeated. In some instances, a separate heater is provided for the filtered oil before it is returned to the bath.
  • No.3,977,973 discloses a heat tube provided in the lower portion of a cooking bath wherein oil is withdrawn from the lower portion of the bath. The withdrawn oil flows through filters and is then re-injected into the bath adjacent the heat tubes. This device is capable of filtering on a continuous basis. Hie food particles, however, must first settle through the bath before they can be drained because oil is withdrawn from the lower portion of the bath only. This requires time, which can allow the food particles to transmit undesirable flavors into the cooking bath.
  • a weir is provided at the surface of the cooking bath and oil is continually allowed to flow over the weir and downward into a sump.
  • TTje oil entering the sump is filtered, reheated, and continually re- ityected into the oil bath. This can be heat inefficient because of the exposed piping.
  • U.S. Pat. No. 5,404,799 describes a filter mechanism placed at the bottom of the tank containing the oil bath so that oil is continuously removed from the oil bath through the filter.
  • Other related oil filtering systems are shown, for example, in U.S.Pat. No.4,768,426 and 4,962,698.
  • US Ser. No. 08/724,233 there is described a continuous filtering system which includes a sump which is disposed beside the fryer tank so that oil from the surface of the tank will continuously spill over the edge of the tank into the sump whereupon it is recycled.
  • the separate filter sump can be removed and the used oil pumped therefrom into a waste container for disposal.
  • a filter sump which is in the form of a pan slidably disposed below the fryer tank with wheels mounted thereon so that when it is desired to clean the tank or remove the used oil therefrom for disposal, the filter pan can be slidably displaced outwardly from the fryer unit for access.
  • the oil filter system has a chassis, a tank for containing oil and heat means for heating the oil in the tank.
  • the filter system comprises: a drain, including a separately controlled outlet and a drain pipe in communication with the oudet.
  • the drain pipe has a down spout; a substantially rectangular, open filter pan disposed below the downspout and a substantially flat filter horizontally disposed within the pan below the downspout whereby oil to be filtered is directed by the downspout onto the upper surface of Ihe filter.
  • the filter is vertically movable within the pan.
  • the present invention seeks to avoid the disadvantages of prior art by providing a more simplified means for ensuring the cleanliness of fluid media such as but not limited to cooking oil in a deep fryer.
  • a filter capable of receiving and retaining unwanted particulate contaminants in a container of cooking oil.
  • the present invention comprises: a filter capable of retention and removal of solid and particularly particulate solids from a cooking medium; the filter including a screen having openings capable of filtering solids of a predetermined size; means to enable immersion in and removal ofthe filter handle from the cooking medium.
  • the filter includes a frame which supports the screen , with the frame including a handle for enabling said immersion and removal of said screen.
  • the screen is preferably in the form a sieve with openings of a predetermined size depending on the size of particulate solids to be removed.
  • the filter is particularly adapted for use in a deep fry industrial cooking vat having oil for cooking foods such as chips and fish.
  • the present invention comprises: a filter capable of retention and removal of solid and particularly particulate solids from a cooking oil; the filter including a filter screen having openings capable of filtering solids of a predetermined size; means to enable immersion in and removal of the filter handle from the cooking medium; wherein, the filter includes a frame which supports the screen, the filter including a handle for enabling said immersion and removal of said screen for cleaning the screen of particulate matter caught by the screen.
  • the filter reduces or eliminates the contaminants at the bottom the vat and reduces the risk of taint ofthe cooking oils . It also allows reduction in costs and labour which would otherwise be spent cleaning the oil vats.
  • the present invention comprises; a removable filter assembly for use in a vat of cooking oil, the filter assembly comprising; a mesh sieve contained in a support structure and handle means to enable immersion and removal ofthe mesh sieve from a cooking medium such as oil; wherein said mesh sieve is detachably fixed to the filter assembly to allow cleaning and /or replacement of said mesh sieve.
  • the present invention comprises: a filter assembly capable of retention and removal of particulate solids from a fluid cooking medium; the filter assembly including a filter screen having openings capable of filtering solids of a predetermined size from the cooking medium; means to enable immersion in and removal of the filter screen from the cooking medium.
  • the means to enable immersion in and removal of the filter screen includes a frame retaining the screen, wherein the frame has associated therewith a handle to enable removal of the assembly from said medium.
  • the screen comprises a mesh with apertures of a predetermined size which prevent solids of a predetermined minimum size passing through the apertures.
  • the support frame includes walls which define a recess in which the mesh screen is disposed. According to a preferred embodiment, the mesh screen is removable from the support frame.
