Definitions

  • This invention relates to a method and apparatus for adding particulate or powdered matter such as flavourings, vitamins and chemical compounds to e.g. a food product (including possibly a pet food product), or a pharmaceutical product. Many such products require the addition of powdered or particulate compounds after their production.
  • “food products” herein are intended to include such other products, and references to “flavouring powder” and the like are intended to embrace other particulate or powdered materials such as vitamins and pharmaceutical compounds.
  • One known method of applying the flavouring to food products after production is an electrostatic process in which food products are subjected to an electrostatic charge whilst in the presence of a powdered flavouring compound.
  • the charging of the food products tends to cause adherence of powdered flavouring compound thereto.
  • Such a method is also useable for applying other particulate or powdered matter to e.g. pharmaceutical products or pet foods.
  • FIG. 1 A known-apparatus for the electrostatic flavouring of food products is shown partly in schematic form in Figure 1.
  • Figure 1 there is shown a flanged, rotatable drum 10 that is mounted in a machine chassis
  • Drum 10 may be driven to rotate by means of a drive wheel
  • Drive wheel 11 having a periphery adapted drivingly to engage the outer periphery of the drum 10.
  • Drive wheel 11 is secured in a bearing 12 and is drivingly connected to a suitable motor (not shown).
  • the cylindrical inner wall of drum 10 carries longitudinally extending vanes 13.
  • the vanes 13 protrude generally perpendicular to the cylindrical inner wall of the drum 10.
  • a transverse carrier bar 14 is secured adjacent the forward end of the drum 10 and supports a hopper assembly 15 that feeds a flavouring nozzle 16.
  • An electrostatic gun 17 is also supported on bar 14.
  • flavouring powder is wasted since it does not become adhered to food products. Therefore, excessive amounts of flavouring powder have to be applied from the hopper system 15 thereby causing clouds of powder to generate in the vicinity of the machine. Powder settles on various parts of the apparatus, thereby making it difficult to keep the apparatus clean; in addition, workers in the vicinity of the apparatus are in danger of inhaling large quantities of flavouring powder.
  • a fluent medium to a product comprising the steps of:
  • an enclosed chamber of reducing cross-section allows the optional use of only a single dispensing region for the fluent medium whilst ensuring that the products are surrounded by a substantially constant density of fluent medium, regardless of the positions of the food products in the apparatus.

  • the electric field is established and the flavouring applied by means of an electrostatic dispensing gun.
  • an electrostatic dispensing gun ie. a combined electrostatic gun and discharge device for fluent media
  • the electric field is established by means of one or more sources of electrostatic charge.

  • the conductive path is provided by contact of the product with a conductive member at a different electrical potential from that of the field.
  • the disjoining of the conductive path may conveniently be caused by the further step of insulating the product or a part thereof from the conductive member. This may advantageously be achieved by moving the product out of conducting contact with the conductive member.
  • the product is moved normal to a surface of the conductive member during the step of insulating.
  • the food product may readily be allowed to fall away from the conductive member under gravity or be blown clear of the conductive member, thereby leading to advantageously simple embodiments of the invention.
  • the product may be moved onto an insulated or insulating member adjacent the conductive member during the step of insulating. This method of insulating the product may be advantageous in the case of products that are particularly delicate and prone to damage if subjected to physical impulses and perturbations.
  • the method additionally includes the step of causing a gas to flow through the region of an electric field during the steps (i) to (iii) identified above.
  • This additional, optional method step assists in ensuring an even distribution of fluent medium throughout the region of the electric field, whilst simultaneously minimising wastage of the medium.
  • the fluent medium is applied simultaneously to a plurality of products moving along a path of travel generally towards a location at which the conductive path is at least partially disjoined, the path of travel being of sufficient length that movement of the plurality of products causes them to settle to a predetermined bed depth, preferably of approximately 2.54 cm ⁇ 1 inch), at the said location. It has been found that the use of a means to cause settling of the product when plural volumes thereof are treated simultaneously advantageously leads to even coating of the products; and settling to an approximately 2.54 cm (1 inch) bed depth produces surprisingly good results.

  • Apparatus according to the invention may be manufactured as an advantageously simple, reliable and robust product. Moreover, such apparatus is highly effective in ensuring the uniform and economical coating of fluent media onto products and minimises the risk of damage to the products themselves.
  • the apparatus includes a plurality of means for creating an electric field. Alternatively, a single such means may be employed.
  • the electric field is created and the fluent medium supplied by one or more electrostatic dispensing guns such as or similar to electrostatic flavouring guns.
  • the means for supporting the product comprises a conveyor for moving the product and formed of a conducting material, whereby when the product contacts the conveyor the conductive path is established.
  • a conveyor to constitute a means for supporting the product and establishing the conductive path means that the product can advantageously be transported through the apparatus whilst simultaneously being treated.

  • the apparatus comprises a first conveyor portion spaced vertically from a second conveyor portion, whereby the product may travel along the first conveyor portion and fall onto the second conveyor portion, the conductive path being disjoined at least partially while the product falls between the conveyor portions.
  • the advantage of this arrangement is that the travel of the product between the first and second conveyor portions is automatic, since the product falls under gravity. Judicious spacing of the first and second conveyor portions ensure that the products are guaranteed to be out of contact with the conveyor for at least a portion of their travel, whilst remaining in the electric field and in the vicinity of the fluent medium.

For instance, it is common in the food industry for gas flushing to be achieved using inert gases so as to avoid tainting food products. The use of an inert gas may also be advantageous in that it is less likely to become charged by the electric field and therefore the risk of discharge elsewhere in the apparatus as the gas is flushed away is reduced.

  • Conveyor 26 is constituted by two separate parts, 26a and 26b, supported at opposite ends of the apparatus 20 and disposed one below the other. Part of conveyor portion 26a lies within chamber 21, and part thereof protrudes from chamber 21 via an aperture in the side wall thereof.
  • Conveyor portion 26a is supported relative to chamber 21 by means (not shown) and by virtue of a vibratory drive 27 in turn mounted via an isolating block 28 on a stand 29 separate from the chamber 21.

  • Conveyor portion 26b is similar to conveyor 26a and is supported generally horizontally on the opposite side of chamber 21 to that of conveyor portion 26a. Conveyor portion 26b is so positioned that its free end inside chamber 21 is vertically below the free end of conveyor portion 26a. Thus, as is visible in Figure 3, any food products reaching the end of conveyor portion 26a fall off the free end thereof into the free end of conveyor portion 26b. Conveyor portion 26a lacks a vertical end wall, to facilitate passage of food products therefrom; conveyor 26b includes an end wall 31 to assist in the catching of falling food products.
