In this paper, via analysis and research on the actual working situation of JK3 type vacuum concentrating equipment we have found that reasons of the reduced function of working are the result of that the vacuum degree of work cuts down and isn't suitable with the temperature of heating and the heat cycle in each evaporator.

The Radiation pressure of a moving ladder-type three-level atom in a squeezed vacuum is discussed.

WT5BZ]We consider the generalized Jaynes-Cummings model with intensity - dependent coupling interacting with a squeezed vacuum.

The steady state behavior of a coherently driven V type three level atom in a bad cavity injected by a squeezed vacuum is considered.

The alcohol-free beer fermented with the technology of the restricted fermentation at the temperature of 16 ℃,and then concentrated with the method of vacuum concentration at the temperature of 65 ℃ had the good taste,and the physic-chemical indexes & the stability agreed with the demand.

A new high-efficiency energy-saving vacuum concentration technology is studied.

After a whole technical process of vacuum concentration, boiling with constant temperature, mixing and dividing, the pickling brine of pickled Mustard tuber is made into pickled Mustard tuber sauce.

Effect of incipient total bacterial count on shelf life of vacuum shrink chilled beef
