Advantages of Controlled Smoking. The conti-olled smokehouse offers many de- 

 cided advantages over the old-fashioned smokehouse: 



1. It is a compact unit, allowing a considerable saving in space. This is par- 

 ticularly important in plants of limited size and in established plants contemplating 

 the installation of a smokehouse. A unit of suitable size could be installed in an 

 unused portion of the plant without interfering with regular operations. 



2. It is equipped for complete control of the smoking procedure which allows 

 for the preparation of a consistently uniform product of good quality. 



3. There is a saving in labor requirements and cost since all operations are con- 

 ducted on one floor. Uniform curing through all sections of the smokehouse 

 chambers eliminates considerable handling; once the trays are loaded with fish for 

 smoking, there is no need for further rearranging or shifting of the product. 



4. It permits a shorter total smoking time as a result of more uniform tempera- 

 ture control, high rate of air-smoke velocity, and proper humidity control. 



5. Through recirculation of the smoke and insulation of the unit the smoking 

 time is reduced and wood and fuel consumption is thereby saved. 



6. The fire hazard is minimized since the smoke generator is a separate unit
