Disclosed are methods and systems for continuously coating food pieces. The methods include a steps of directing and uncoated food stream through an enrober to apply a first coating to at least a portion of a surface of each food piece to form a coated stream and continuously redirecting a portion of the coated stream back through the enrober along with the stream of uncoated food pieces to apply at least one additional coating to the portion of the coated stream.

A curtain applicator for applying a liquid or pasty application medium to at least one surface of a running material web, in particular a fibrous web. The curtain applicator has an applicator nozzle, in particular a slotted nozzle, which under the effect of gravity, and optionally with further forces, is suitable for dispensing a single-tier or multi-tier curtain onto the surface of the material web. The curtain applicator further has a wiping device which is suitable for keeping entrained air carried by the material web away from the curtain. Moreover, there is provided at least one further blocking device which is suitable for keeping air movements of the ambient air away from the curtain.

A device for applying a treatment substance to a running paper web or board web (11) by means of at least one curtain applicator (2.1, 2.2) comprising a curtain coating die for applying the treatment substance to an applicator roll (6, 7) which, together with a second roll (6, 7), creates a treatment nip (15) in which the treatment substance is transported from the applicator roll (6, 7) to the respective side of the paper web or board web (11), and the curtain coating die has a slot adjustment (3.1, 3.2) for adjusting an exit slot (14.1, 14.2). To provide a device for applying treatment substances which improves the paper/board quality differently prepared treatment substances can be supplied to the at least one curtain coating die, and the curtain applicator (2.1, 2.2) combines the two operating modes of a film operation mode and a sump operation mode by providing an electrically and/or mechanically actuable adjusting device for the slot adjustment (3.1, 3.2) applied to the exit slot (14.1, 14.2) of the curtain coating die, which controls a die lip and sets the exit slot (14.1, 14.2) alternatively to 100 m to 500 m for a film operation mode or to 500 m to 2.0 mm for a sump operation mode, so that the at least one curtain applicator (2.1, 2.2) is designed to be performed with two different operating modes.

An apparatus and a method for performing liquid treatment with respect to a substrate are provided. The apparatus includes a substrate supporting unit that supports and rotates the substrate, and a liquid supplying unit that supplies a liquid onto the substrate supported by the substrate supporting unit. The liquid supplying unit includes a nozzle unit that supplies a first treatment liquid and a second treatment liquid, and a moving unit that moves the nozzle unit. The nozzle unit has a first slit discharge port for discharging the first treatment liquid in a liquid curtain manner, a second slit discharge port for discharging the second treatment liquid in the liquid curtain manner, and a wetting liquid discharge port for discharging a pre-wetting liquid. The treatment liquids are selectively supplied depending on films formed on the substrate, thereby easily coping with the substrate having various types of films.

Disclosed is a slot coater, which includes a feeding unit having a passage through which a coating fluid flows in, a manifold for accommodating the coating fluid supplied through the feeding unit, a discharge unit communicating with the manifold to discharge the coating fluid accommodated in the manifold, a plurality of shim plates arranged at regular intervals in a length direction of the manifold, and a temperature control unit for generating a temperature difference between a shim plate located relatively closer to the feeding unit and a shim plate located respectively farther from the feeding unit.

The present disclosure provides apparatuses and methods for non-contact printing on comestible products. The apparatus includes an extruder for extruding a slab of an edible substrate and a non-contact printing device for printing an edible ink on the slab. The apparatus provides versatility as the printing device may be placed anywhere along the apparatus. The printing device may be positioned along the apparatus as desired to operate in cooperation with other components of the apparatus.

An asphalt shingle manufacturing machine that includes a curtain die for applying a liquid release layer on an asphalt coated substrate. The moisture of the liquid release layer evaporates leaving a dispersed solid particulate release layer. The curtain die includes a first body section and a second body section with a shim disposed between the body sections to define a distribution channel. The second body section may include chamber manifold defined therein to store a volume of liquid release agent. The distribution channel places the chamber manifold in fluid communication with a discharge outlet of the curtain die in order to disperse a volume of liquid release agent from a chamber manifold out of the discharge outlet. The shim may be configured to define a width of the distribution channel to determine the flow rate and discharge pattern of the liquid release agent.

A curtain coating device includes a curtain coating member, a conveyance unit, a separation member, and a base material supporting member. The curtain coating member creates a curtain-like film of coating liquid and makes the curtain-like film flow down. The conveyance unit conveys a base material to which the curtain-like film is to be applied. The separation member includes a receiving portion inclined downward from inside to outside in a width direction of the curtain-like film, and separates an end portion of the curtain-like film having flowed down by receiving the end portion with the receiving portion above the base material. The base material supporting member is disposed inside in the width direction of the curtain-like film than the receiving portion of the separation member, and supports the base material on an upper side flat portion while the base material is being conveyed.
