Abstract

A method and apparatus designed to insure the integrity of food and food service in vending cart. Specifically, disclosed is a system that ensures the integrity of the food will not be compromised, by providing an enclosed or environmentally protected food service station, either portable, mobile or stationary. The system may also provide food monitoring for security, time, temperature and transaction accounting. The system consists of an enclosed or environmentally protected food service station, a sealed food compartment in which food is served, a food storage compartment, an access door for providing service and cleaning to the sealed sections of the station, and optionally an integrated security system that ensures that all access doors and ports are monitored for access and integrity. The security system provides an alarm and reporting capability. Authorization codes are provided to control alarm reset and accounting features of the system.

Claims

1. A food vending system, comprising:

(a) a secure bulk food storage area, having a bulk food storage space;

(b) a secure food preparation area wherein a portion of bulk food is received from said secure bulk food storage area and manipulated;

(c) an access port in said secure food preparation area, having physical barrier for preventing contamination of said secure food preparation area while permitting manual manipulation of the portion of bulk food therein; and

(d) a unidirectional delivery port for external delivery of manipulated food,

wherein said secure bulk food storage area and said secure preparation area are tamper evident.

2. The system according to claim 1, wherein said secure bulk food storage area is provided with a locked access door for restocking.

3. The system according to claim 1, wherein said secure food preparation area is provided with a locked access door for cleaning.

4. The system according to claim 1, further comprising a sensor system for detecting unauthorized access to said secure bulk food storage area and said secure food preparation area.

5. The system according to claim 4, wherein said system comprises a control for detecting an authorized access request, said authorized access request comprising a secure code transmitted to said control.

6. The system according to claim 4, wherein said system for detecting unauthorized access comprises an alarm having a reset, said reset being activated by a secure code transmitted to said control.

7. The system according to claim 5, wherein said code is transmitted by means selected from the group consisting of a wired interface, a radio frequency interface, an infrared interface, a voice interface and a biometric detection interface.

8. The system according to claim 6, wherein said code is transmitted by means selected from the group consisting of a wired interface, a radio frequency interface, an infrared interface, a voice interface and a biometric detection interface.

9. The system according to claim 1, wherein said secure bulk food storage area is secure against unauthorized food substitution.

10. The system according to claim 1, wherein said secure bulk food storage area is adapted to store and separately retrieve a plurality of different types of foods, each being separately retrievable.

11. The system according to claim 1, further comprising a database storing information relating to an operation of the system.

12. The system according to claim 1, wherein said physical barrier allows direct manual manipulation of the portion of bulk food in said secure food preparation area.

13. The system according to claim 1, wherein said physical barrier comprises at least one glove extending into said secure food preparation area.

14. A method for vending food, comprising:

(a) providing a secure bulk food storage area, having a bulk food storage space from which selected portions are delivered;

(b) manually manipulating delivered food portions in a secure food preparation area while preventing contamination thereof; and

(c) externally expelling the manipulated food from the secure food preparation area through a unidirectional delivery port,

wherein said secure bulk food storage area and said secure preparation area are isolated from the use and tamper evident.

15. The method according to claim 14, further comprising the step of providing said secure bulk food storage area with a locked access door for restocking.

16. The method according to claim 14, further comprising the step of providing said secure food preparation area with a locked access door for cleaning.

17. The method according to claim 14, further comprising the step of detecting unauthorized access to said secure bulk food storage area and said secure food preparation area.

18. The method according to claim 17, further comprising the step of detecting an authorized access request, said authorized access request comprising a secure code transmitted to said control.

19. The method according to claim 17, further comprising the step of detecting unauthorized access and producing a resettable alarm, said alarm being reset by a secure code transmitted to said control.

20. The method according to claim 18, further comprising the step of transmitting said secure code by means selected from the group consisting of a wired interface, a radio frequency interface, an infrared interface, a voice interface and a biometric detection interface.

21. The method according to claim 19, further comprising the step of transmitting said secure code by means selected from the group consisting of a wired interface, a radio frequency interface, an infrared interface, a voice interface and a biometric detection interface.

22. A system for ensuring compliance with dietary laws in a food vending device, comprising:

(a) a secure food storage chamber;

(b) a food preparation chamber, receiving food from said storage chamber, for manually controlled manipulation thereof through an access port having a contamination barrier, said food storage chamber and said food preparation chamber being physically isolated from external contaminants; and

(c) an external unidirectional food exit port from said food preparation chamber.

23. The system according to claim 22, wherein said contamination barrier comprises at least one glove extending therein.

24. The system according to claim 22, further comprising a mechanism for limiting access from said food preparation chamber to said food storage chamber.

25. The system according to claim 22, further comprising an intrusion detection system, storing an indication of an intrusion condition.

26. The system according to claim 25, wherein said intrusion detection system comprises an electronic control and an interface for receiving an intrusion condition reset code.

27. A food vending system ensuring food environment integrity, comprising:

(a) a multiserving food storage area;

(b) a food preparation area, adapted for receipt and manual manipulation, through a barrier, of a serving of food from the multiserving food storage area;

(c) a user interface for manually controlled manipulation of food without direct human contact therewith in said food manipulation area; and

(d) a delivery port for external delivery of a manipulated serving of food,

wherein said food storage area and said food preparation area are environmentally protected.
