Device for heating a substance in through-flow
First Claim
1. A device for heating a substance or a mixture of substances in through-flow, in particular for boiling a raw material for the preparation of a confectionery product or similar luxury food product, said device comprising:
- a) a closed housing;
b) at least one feed pipe for a heating fluid;
c) at least one discharge pipe for said heating fluid;
d) two plate-shaped end elements each having a plurality of end-element apertures;
e) two outside cover plates, each having an inward-facing surface, and each covering one said end element;
f) a number of straight pipe sections running essentially parallel to each other and extending internally through said housing, between said plate-shaped elements, said pipe sections each having ends and said pipe section ends being mounted in said end-element apertures;
g) recesses in said inward-facing surface of each said cover plate, said recesses providing flow path connections between pairs of said apertures in such manner that said pipe sections are interconnected at said ends to form a single, multiple pass flow path in said housing, said flow path extending between said feed and discharge means;
h) an externally communicating aperture in at least one said cover plate for connection to a feed pipe for said substance to be heated; and
i) a valve element carried by said apertured cover plate;
wherein said valve element is movable to block one of said connections between a pair of said end-element apertures to reduce the capacity of said device.

Abstract
Device for heating a substance in through-flow, comprising a closed housing (1) and a number of straight channels (8) extending between two plate-shaped elements (2, 3), each provided with apertures (6, 7) in which the ends of the channels are mounted, and which are covered by a cover plate (9, 10) in which recesses (11, 12) are disposed, forming connections between the pairs of apertures (6, 7), while an aperture (18) is provided in a cover plate (10), which aperture runs through said cover plate and can be connected to the feed pipe (16) for the substance to be treated, and a valve element (19) is fitted in the cover plate (10), by means of which element the connection between the aperture (18) and the aperture (7) in the plate-shaped element lying upstream thereof can be blocked. A channel can be formed by a number of pipe sections running parallel to each other and each mounted in a member disposed in one of the apertures in the plate-shaped element.

5. A device for heating a substance or a mixture of substances in through-flow, in particular for boiling a raw material for the preparation of a confectionery product or similar luxury food product, said device comprising:
-
a) a closed housing; b) at least one feed pipe for a heating fluid; c) at least one discharge pipe for said heating fluid; d) two plate-shaped end elements each having a plurality of end-element apertures; e) two outside cover plates, each having an inward-facing surface, and each covering one said end element; f) a number of straight pipe sections running essentially parallel to each other and extending internally through said housing, between said plate-shaped elements, said pipe sections each having ends and said pipe section ends being mounted in said end-element apertures; g) recesses in said inward-facing surface of each said cover plate, said recesses providing flow path connections between pairs of said apertures in such manner that said pipe sections are interconnected at said ends to form a single, multiple pass flow path in said housing, said flow path extending between said feed and discharge means; and h) an externally communicating aperture in at least one said cover plate for connection to a feed pipe for said substance to be heated; wherein each said pipe section comprises a bundle of pipe sub-sections running essentially parallel to one another, said pipe sub-sections of a bundle constituting each pipe section having two subsection ends both said sub-section ends being mounted in a tubular element said tubular element being mounted in one of said end-element apertures.
