Fluidized Bed Reactor And Distribution System

US Patent:
5330652, Jul 19, 1994
Filed:
Feb 26, 1993
Appl. No.:
8/023323
Inventors:
Joshua N. Goldman - Montague MA
John R. Rosenau - Amherst MA
Assignee:
Aquafuture, Inc. - Turners Falls MA
International Classification:
C02F 306
US Classification:
210618
Abstract:
This invention provides a fluidized bed reactor with improved method and apparatus for inhibiting and clearing clogging of the fluid distribution network in such reactor. In particular, at least one channel or reservoir of fluid is provided over at least a selected portion of the distribution network, with fluid from such column/reserve being released to maintain flow and pressure in the distribution network as the media bed is defluidized. For the preferred embodiment, the fluid column is (a) a feed pipe connecting a fluid inlet which is above the reactor fluid level to the distribution network; and (b) a plurality of risers which, for the preferred embodiment, extend from the end of each lateral tube of the distribution network. A vacuum breaker is provided for each fluid column to permit fluid to flow from the column into the network when pressure is removed. A valve controlled opening may be provided at the top of each riser to permit purging of the distribution network through the openings when the valve is opened and to provide access to the distribution network for clearing clogs without requiring removal of the media bed.

Preparation Of Dairy-Based Cheese Food

US Patent:
4066800, Jan 3, 1978
Filed:
Nov 30, 1973
Appl. No.:
5/420444
Inventors:
John R. Rosenau - Amherst MA
John C. Anderson - St. Paul MN
Assignee:
The Regents of the University of Minnesota - Minneapolis MN
International Classification:
A23C 1902, A23C 1912
US Classification:
426582
Abstract:
A dairy based cheese food is prepared by a process involving heating milk to pasteurize and denature whey proteins, acidifying the milk to form curd and whey, separating the curd from the whey, neutralizing the curd by adding a base, mixing an acid with the neutralized curd to reacidify, mixing an additive with the curd, manipulating the curd such as by extrusion, and packaging the curd.
