Filed: 1980-07-30
Abstract: Known designs of pilger roll have a typical working angle of 180 DEG to 210 DEG  which is divided into three regions; the jaw, the finishing groove, and the delivery zone. The present invention seeks to optimize the profiles of the respective zones so that a single curve can define both the jaw and the delivery zone and provide an increased working angle. According to the invention the jaw comprises a linear rear portion over about 25 DEG  of rotation preceded by a portion defined by the curve:  y = d (a + b . e<cx>)<n> where d, a, b, and c are constants dependant upon the diameter of the roll body. The jaw and the delivery zone are symmetrically arranged on either side of the finishing groove, and the zones are in the ratio 36%, 28%, and 36%. <IMAGE>

Title: Method for preparation of delicious fish products a la "sliced salmon" by way of salting herring fish fillet without sterilization
Inventor: SUBINS KONSTANTINS
IPC: A23B4/02
Filed: 2001-02-08
Abstract: This invention pertains to the field of making delicious fish products using herring fish. The method may be implemented using frozen herring fish fillet as semi-finished product as well as using fresh fillet. The method offered is characterised in that salting process is made in two steps. The first step contains salting non-sliced fish fillet together with skin in maximally saturated solution of salt and preservatives by following equalisation of salt in fish fillet. After that, the fish fillet are separated from skin just before second salting process. The fillet may be cut in 10 to 15 mm slices by perpendicular section according longitudinal axe of fillet. The cutting process is implemented slantwise at an angle of 20 to 45 grade according horizontal surface, from head to tail. The second-step of the salting process and a saturation process with dye-stuffs as food additives could be combined. After pouring off the slices are packed, an infusion is added and tin is sealed. The described method allows to consider the obtained herring fish products as delicious fish products.

After preparing carry sousing in culinary salt liquid with consistence 1.15-1.20 g/cm<3>, salt liquid and fish volume proportion corresponds to 2:1, the liquid temperature cannot be higher than 15 degrees C, the fish are sustained in liquid until the salt consistency in the fish reaches 1.0-2.5 % of the volume. Then the fish are threaded through the eyes, mouth and gills on picks with 2-2.5 cm spacing, rinsed, put in frames and kept for 30-40 min, for spare water sapping from surface, then dried for 15-30 min at 40-60 degrees C, boiled in hot steam of 90-140 degrees C and smudged at 80-120 degrees C. Boiling and smudging duration is 1-1.5 hours, after that the fish cool and are treated, splaying heads with gills in straight sections and pre-packing in tins. At the same time they are heated with seed oil or a seed oil mixture up to 112-120 degrees C and kept for 25-30 min. After pre-packing, the fish are transfused with the prepared oil at 75-80 degrees C and sterilized. For smoking wood, pulp of alder is used.
