Abstract
Abstract An apparatus comprises a cylindrical casing having a pipe for admitting starting material. An auger feeder is accommodated in the casing having a working head and a nozzle having a central passage for feeding out hydrolysate mass. The nozzle is connected to the casing and is mounted coaxially with and in a radially spaced relation to the head. The working head comprises two truncated cones interconnected at larger bases thereof and is rigidly secured to the auger feeder. The central passage of the nozzle is made narrowing towards the outlet and embraces the second truncated cone of the head in the path of flow of the starting material.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
258 words
Apparatus for mechanical and chemical destruction of polysaccharides of younger slightly decomposed peat comprising, a tubular casing of constant inner diameter, a driven auger feeder in said casing for conveying starting material axially along the casing, means defining an inlet for introducing starting material into said casing, a nozzle having a central passage in communication with said casing and defining an outlet from said tubular casing axially spaced from said inlet, a working head on an end of said auger feeder and rotationally driven thereby, said working head comprising two frustoconical cones connected along larger bases thereof, a first of said frusto-conical cones having a taper and progressively increasing in diameter in a direction of material flow in said casing toward said outlet and defining with inner cylindrical surfaces of constant diameter of the tubular casing a working annular space gradually decreasing axially in cross section within which material being treated in said casing is progressively compressed, mixed and treated, a second of said frusto-conical cones having a shorter axial length than said first cone and tapering toward the axis of said auger feeder and in a direction toward said outlet, said nozzle having an internal tapered passage having a converging portion at least partially circumferentially of said second cone spaced therefrom and having a taper corresponding to the taper of said second cone and defining with said second cone a working zone a desired volume of uniform cross section in which mechanical and chemical destruction of polysaccharides in said material takes place to yield a homogeneous hydrolysate.

Claim 3
Dependent Claim
56 words
Apparatus for mechanical and chemical destruction of polysaccharides of younger slightly decomposed peat according to claim 1, in which said first cone has axial ribs circumferentially spaced thereon, said ribs being inclined relative to the longitudinal axis of said casing and working head, and the ribs having a greater inclination in a direction toward said inlet.
Claim 4
Dependent Claim
22 words
Apparatus according to claim 2, in which said inclination is in the order of 15° to 20° relative to said longitudinal axis.
Claim 5
Dependent Claim
21 words
Apparatus according to claim 1, in which said nozzle is movable axially relative to said second cone on said working head.
