Abstract
An improved condenser system for condensing vapor containing liquid or solid particles to minimize contamination of the condenser system by such particles and to increase the efficiency of liquid processing systems, including extracting particles from the vapor producing processing and cool down of the liquid and returning the particles to the processing container without fouling the condenser system or losing product.

A condenser cooling and temperature control system for condensing the vapor resulting from the processing of a boiling batch not containing resin, comprising:
- (a) an enclosed container for cooking or cooling a batch not containing resin, and including a first opening in said container for receiving a vapor recovery line means and a second opening in said container for receiving a reflux line means;
- (b) a condenser means for condensing the vapor produced during the processing of said boiling batch in the container;
- (c) a vapor recovery line means in communication with said first opening and with the condenser means whereby vapor and particles resulting from the processing of said batch are permitted to escape from the container and vapor is transported to the condenser;
- (d) a vacuum pump means and a vacuum line located downstream of said condenser means for establishing a pressure differential between said condenser means and said vacuum line whereby the vapor and particles from the processing of said batch are drawn from the container through the vapor recovery line means and through the condenser means;
- (e) a reflux line means for carrying a condensate from the condenser means to the enclosed container, said reflux line means having a positive pressure;
- (f) an entrainment extraction means providing removal of particles from the vapor drawn from the container and introduced into the vapor recovery line means, said entrainment removal means being located before the introduction of said vapor into said condenser means;
- (g) a means for determining the pressure differential between the container and the vacuum line;
- and
- (h) at least one alternative vapor recovery line means for routing vapor and particles resulting from the processing of said batch from said container to said condenser means, and a flow directing means in communication with said alternative vapor recovery line means, wherein said entrainment extraction means is bypassed in response to a reduction of said pressure differential by a predetermined amount.
