product introduction

fish meal as an important animal protein add feed, which  could not be replaced by other feed, the world's major producer of fish meal is peru, chile, japan, denmark, the united states, former soviet union and norway, the annual worldwide demand of fish meal is enormous, in addition, the fish oil which is subsidiary of fishmeal is also has big proportion of health care market in the world. our company counter to domestic and international production situation, development of a variety of specifications with the shore, marine fish meal production line series equipment, after treatment the fish meal protein consent can attain above 60%, meet the best quality fish meal standard, the equipment meet to the daily processing capacity is 50 tons, 80 tons, 100 tons, 150 tons, 300 tons of fish meal production plant.our fish meal production machine is complete set of equipment , which including raw material transportation, steamer, squeezer,         concentration and separation, wastewater treatment and a series of other processes.

description of the main units for wet type continuous fish meal production

1.steamer(directly of indirectly steaming stock)
the shell jacket, the intermediate shaft and the helical blade of the steamer provide indirect steam heating. the feed steam calandrias on both sides of the steamer shell provide direct steam heating.

2.squeezer (expelling most of the water in steamed stock by squeezing)
(1).single-screw squeezerthe single-screw squeezer has a tapered intermediate shaft and the helical blade with variable pitch, forming a decreasing space to provide squeezing. it can well expel most of the water and fat in fish stock.
(2)double-screw squeezerthe double-screw squeezer has a tapered intermediate shaft and the helical blade with variable pitch, and can squeeze fish stock and expel most of the water and fat.

3.continuous dryer (continuously feeding fish cake at the front end and discharging fish meal at the rear end)
(1). annular-tube type continuous dryer
the dryer shaft is welded with several sets of annular tubes, each of which is comprised of several layers of concentric annular tubes with different diameters. steam feeding and water returning are respectively through the whole tubes.
(2). plate-and-tube type continuous dryer
the dryer shaft is welded with several iron discs in equal spacing. each iron disc is welded on both sides with the tubes in semi-circular section that is cut of seamless tube into two halves and bent in archimede’s spiral. fish meal can be stirred between two adjacent discs by the semi-circular spiral tubes on both sides and kept in full contact with the heating surface. steam feeding and water returning are respectively through the semi-circular tubes.
(3). spiral-tube/plate type continuous dryer (new type with chinese patent )
the dryer shaft is welded with several sets of multi-layer non-concentric seamless tubes, each of which is comprised of multiple seamless tubes having different sizes bent in archimede’s spiral. steam feeding and water returning are respectively through the whole tubes. the spiral-tube dryer has the advantage of the annular-tube dryer in steam feeding and water draining and the good performance of the plate-and-tube dryer in fully stirring fish meal. these three kinds of dryers, i. e. the annular-tube dryer, the plate-and-tube dryer and the spiral-tube/plate dryer, are classified into the design of the dryer shell with steam jacket and the design without steam jacket.
