  • Patent number: 11629558
    Abstract: The invention relates to a melting head (1) for an ice melting apparatus (1, 8) comprising a rear, in relation to the propagation direction, attachment region (4) for attaching to a drilling apparatus (8) or a drilling rod assembly, and a forward, in relation to the propagation direction, heatable front region (1c), wherein the front region (1c) has a radially outer face region (1a) in which the front region (1c) has an outer cross section that tapers in the propagation direction (3) up to the forward axial melting head end (1d), in particular with a tapering outer diameter, and the radially outer face region (1a) surrounds an inner cavity (5), the free inner cross section of which reduces from the axial melting head end (1d) counter to the propagation direction (3). The invention also relates to an ice melting apparatus (1, 8) formed with the melting head (1).

  • Patent number: 8679256
    Abstract: A soft, spreadable honey product is formed by feeding the honey in raw solid form through a side feed chute into a container defined by a vertical rotating auger with a clearance between the flight and the container. The auger flight drives the material to one discharge end of the container with a closed discharge valve at the discharge end to cause the honey to be admixed within the container and the crystals to fracture and to interact with one another so as to grind them down making them smooth and small. The mixing action is carried out until the crystals in the honey are broken down sufficiently to form the honey into the soft, spreadable honey product and carried out without the use of any heat at any time and without filtering the product.
