Patent number: 9108872Abstract: The invention relates to a device and a method for the separation of solids from a biowaste slurry before heat treatment, and for heat treatment of the separated solids. The device comprises a chamber with a main inlet port for feeding slurry, and outlet ports. A unit for separating solids is adapted to an outlet port so, that liquid leaving the chamber has passed through the separation unit. A second outlet port is provided directly from the chamber to allow removal, following sterilization, of solids collected in the chamber. The sterilization is secured by temperature monitoring at representative locations.Type: GrantFiled: May 19, 2014Date of Patent: August 18, 2015Assignee: STERIS Europe, Inc. Suomen SivuliikeInventors: Mauri Salmisuo, Juha Mattila, Teppo Nurminen

Patent number: 8961874Abstract: According to the present invention a method for heat recovery in a device for the sterilization of biological material is provided. The present method eliminates the risk of contaminating the sterilized effluent with unsterilized biological material via the heat recovery system. In a device according to the invention, a heat recovery circuit is provided for transferring heat from the sterilized effluent stream to the biologically hazardous feed stream. Protection against contamination through leaks is obtained by maintaining at all times a pressure difference preventing biologically hazardous material from bypassing the heat treatment and flowing in the direction of the sterilized material.Type: GrantFiled: June 14, 2011Date of Patent: February 24, 2015Assignee: Steris Europe, Inc.

Patent number: 7211229Abstract: Continuous biowaste sterilization process, the operability of which is ensured in such a way that during process startup, extreme conditions possibly coming into question during operation are simulated, i.e. the greatest possible flow rate and the lowest temperature of the feed flow. In the startup stage, a liquid to be sterlized is circulated in the apparatus, until the capacity has been ascertained, whereafter the discharge stream can be conducted to a sewer system. The apparatus according to the invention comprises, in the flow direction of the biowaste-containing liquid, a storage tank, at least one feed pump capable of delivering a constant flow, at least one heating unit, at least one cooling unit, and a circulation circuit for circulating the biowaste-containing liquid through the heating unit, as well as connecting piping and valves. By means of specific piping and valve arrangements it is also ensured that all parts of the apparatus can be sterilized for maintenance purposes.Type: GrantFiled: October 7, 2002Date of Patent: May 1, 2007Assignee: Steris Europe Inc.
