Abstract

Disclosed herein is a cold smoke smoker for cold smoking foods using materials heated to a controlled temperature for use in food service, commercial, and residential environments. The cold smoke smoker comprises a blower fan which blows smoke up through a vent, past an ignition plate smoking the materials, and through tubing into a food package containing food. The materials that are smoked can include natural wood chips, herbs, spices, or blends of the fore mentioned materials.

Claims (65)

1. A smoker comprising:

a blower fan;

an ignition plate positioned above the blower fan,

wherein a top surface of the ignition plate has a concave surface;

an ignition chamber cover for removably covering the ignition plate to create an ignition chamber;

a smoke outlet on a top surface of the ignition chamber cover, located above the ignition plate when the ignition chamber cover covers the ignition plate, for releasing smoke from the ignition chamber to smoke a product;

a control panel for controlling a speed of the blower fan or a temperature setting of the ignition plate;

a temperature controller for controlling a temperature of the ignition plate in response to the temperature setting from the control panel;

a vent plate having a plurality of vent areas,

wherein each of the plurality of vent areas comprises a plurality of vents,

wherein the vent plate is positioned above the blower fan and below the ignition plate,

wherein the plurality of vent areas do not extend directly under a bottom surface or periphery of the ignition plate,

wherein the blower fan blows air through the plurality of vent areas and blows smoke out the smoke outlet for smoking the product, and

wherein the blower fan causes a chimney effect for the air and the smoke within the ignition chamber.

2. The smoker according to claim 1 , further comprising:

a section of tubing coupled to the smoke outlet for directing smoke from the ignition chamber to an inlet of a food container.

3. The smoker according to claim 1 , further comprising:

a materials plate having a same shape as the top surface of the ignition plate, wherein materials smoked in the smoker are placed on the materials plate.

4. The smoker according to claim 1 , wherein an air inlet of the blower fan is covered by a debris filter.

5. The smoker according to claim 1 , wherein the ignition chamber cover further comprises:

a plurality of sidewalls,

wherein each sidewall of the plurality of sidewalls is formed from an outer layer, a middle layer, and an inner layer.

6. The smoker according to claim 5 , wherein the outer layer and the inner layer are formed from stainless steel, and wherein the middle layer is formed from an insulating material.

7. The smoker according to claim 1 , wherein the ignition plate is a ceramic infrared heater with an operating range of 400°-800° F.

8. The smoker according to claim 7 , wherein the ignition plate comprises a plurality of thermocouples spaced in the ceramic infrared heater.

9. The smoker according to claim 1 , further comprising:

a pan having a handle and a base with a longitudinal cutout,

wherein a size of the base is approximately the same as a size of the vent plate, and a length of the cutout is approximately half a length of the vent plate.

10. The smoker according to claim 1 , wherein the vent plate comprises a raised lip surrounding the vent plate, and wherein a bottom surface of the ignition chamber cover releasably mates with the raised lip to form an airtight seal in the ignition chamber.

11. A smoker system comprising:

a cold smoker comprising:

a blower fan;

a vent plate having a plurality of vent holes,

wherein the vent plate is centered in a position directly above the blower fan, and

an ignition plate centered above the blower fan,

wherein the plurality of vent holes are not located in any area of the vent plate directly below a bottom surface of the ignition plate, and

wherein the vent plate is positioned above the blower fan and below the ignition plate;

at least one material to be smoked placed on a top surface of the ignition plate;

an ignition chamber cover for removably covering the ignition plate to create an ignition chamber;

a smoke outlet on a center of a top surface of the ignition chamber cover for releasing smoke from the ignition chamber;

a control panel for controlling a speed of the blower fan or a temperature setting of the ignition plate; and

a temperature controller for controlling a temperature of the ignition plate in response to the temperature setting from the control panel; and

a section of tubing with a first tubing tip coupled to the smoke outlet and a second tubing tip; and

a food container for receiving smoke from the smoke outlet, the food container comprising:

an inlet opening coupled to the second tubing tip;

a chamber for holding one or more food products; and

an outlet opening for evacuating smoke and air from the chamber.

12. The smoker according to claim 11 , wherein the outlet opening is coupled to a section of an outlet tubing that evacuates the smoke and the air from the chamber to a smoke filter.

13. A method for cold smoking a food product using a smoker, the method comprising:

placing a material to be smoked on a top surface of an ignition plate of the smoker;

selecting a smoking temperature for the ignition plate using a temperature control panel;

covering the ignition plate with an ignition chamber cover to form an airtight seal surrounding the ignition plate;

powering the ignition plate to cause the ignition plate to reach the smoking temperature and cause the material to smoke;

powering a blower fan to cause smoke to exit a smoke outlet on a top surface of the ignition chamber cover; and

coupling a section of tubing from the smoke outlet to a smoke inlet of a container holding the food product to allow the food product to be cold smoked,

the smoker comprising:

a vent plate having a plurality of vent areas,

wherein the vent plate is positioned above the blower fan and below the ignition plate,

wherein the plurality of vent areas are not located on the vent plate in an area under a bottom surface of the ignition plate or a periphery of the ignition plate, and

wherein the blower fan blows air through the plurality of vent areas towards the smoke outlet to create a chimney effect within the ignition chamber.

14. The method according to claim 13 , further comprising:

coupling an outlet of the container to a smoke filter for evacuating smoke from the container.

15. The method according to claim 13 , wherein the material is selected from wood chips, herbs, or a combination thereof.

16. The method according to claim 13 , wherein the ignition plate is an electric heating element.

17. The method according to claim 16 , wherein the electric heating element is a coil, a cartridge, a cast-in heater, a ceramic infrared heater, or a flexible kapton heater.
