## Abstract

A method and an installation are provided for preserving desired seasoning flavor profiles during the manufacturing of food-seasoning sheets. The method includes the steps of; laying a thin layer of adhesive on a base sheet; removing air from the adhesive prior to the step of laying; reducing free moisture from the adhesive during the step of laying, and depositing food-seasoning ingredients onto the thin layer of adhesive. The installation for manufacturing food-seasoning sheets includes an adhesive dispenser having a reservoir and a delivery slot communicating with the reservoir for dispensing adhesive. The dispenser has a heating element mounted thereto for heating the adhesive. The adhesive is made under a partial vacuum and it is conveyed to the dispenser in a partial vacuum.

## Claims

### Claim 1

An installation for preserving seasoning flavour profiles during the manufacturing of food-seasoning sheets having a layer of adhesive laid onto on a base sheet, comprising;
a first reservoir;
a liquid adhesive dispenser having a slot die and a second reservoir in said slot die for receiving said liquid adhesive from said first reservoir and a delivery slot in said slot die communicating with said second reservoir for dispensing said liquid adhesive onto said base sheet;
a piping system including a pump for pumping said liquid adhesive from said first reservoir to said second reservoir;
said first reservoir being a sealable reservoir having a mixer mounted therein and a vacuum pump connected thereto for generating a hermetical environment in said first reservoir when said liquid adhesive is being made in said first reservoir; and for removing air from said liquid adhesive prior to delivering said liquid adhesive to said second reservoir;
said piping system having a first tubing mounted to said first reservoir and a second tubing mounted to said second reservoir; said piping system being hermetically sealed between said first reservoir and said second reservoir; and
said second reservoir having air-and-free-moisture removing equipment mounted thereto for removing air and free moisture from said liquid adhesive prior to depositing said liquid adhesive to said base sheet.

### Claim 2 (depends on 1)

The installation as claimed in claim 1 wherein said air-and-free-moisture removing equipment comprises a first, second and third complementary air-and-free-moisture removing devices.

### Claim 3 (depends on 2)

The installation as claimed in claim 2 wherein said first air-and-free-moisture removing device is a vacuum box mounted below a delivery slot of said slot die.

### Claim 4 (depends on 2)

The installation as claimed in claim 2, wherein said second air-and-free-moisture removing device is a heating element mounted in said slot die and a vent hole in said second reservoir for reducing air and free moisture in said liquid adhesive in said second reservoir when said liquid adhesive in said second reservoir is heated.

### Claim 5 (depends on 4)

The installation as claimed in claim 4, wherein said third air-and-free-moisture removing device is a pull-back valve mounted to said second reservoir for creating a partial vacuum in said liquid adhesive in said second reservoir, and for removing air and free moisture in said liquid adhesive in said second reservoir.

### Claim 6 (depends on 5)

The installation as claimed in claim 5, wherein a stroke of said pull-back valve is selected to break a flow of adhesive through said slot die without introducing air in said second reservoir.

### Claim 7 (depends on 3)

The installation as claimed in claim 3, wherein said vacuum box is mounted to said slot die in such a way for removing air from said base sheet prior to depositing said liquid adhesive to said base sheet.

### Claim 8 (depends on 7)

The installation as claimed in claim 7, wherein said vacuum box is mounted to said slot die is such a way for removing air and free moisture from a lower laminae of said liquid adhesive.

### Claim 9

An installation for preserving seasoning flavour profiles during the manufacturing of food-seasoning sheets having a layer of adhesive laid onto on a base sheet, comprising;
a first reservoir;
a liquid adhesive dispenser having a slot die and a second reservoir in said slot die for receiving said liquid adhesive from said first reservoir and a delivery slot in said slot die communicating with said second reservoir for dispensing said liquid adhesive onto said base sheet;
a piping system including a pump for pumping said liquid adhesive from said first reservoir to said second reservoir;
said first reservoir being a sealable reservoir having a mixer mounted therein and a vacuum pump connected thereto for generating a hermetical environment in said first reservoir when said liquid adhesive is being made in said first reservoir, and for removing a first amount of air from said liquid adhesive when said liquid adhesive is in said first reservoir;
said piping system having a first tubing mounted to said first reservoir and a second tubing mounted to said second reservoir; said piping system being hermetically sealed between said first reservoir and said second reservoir; and
said second reservoir having air-and-free-moisture removing equipment mounted thereto for removing air and free moisture from said liquid adhesive prior to depositing said liquid adhesive to said base sheet; said air-and-free-moisture removing equipment comprising;
a heater mounted in said second reservoir for heating said liquid adhesive and for removing a second amount of air and free moisture from said liquid adhesive in said second reservoir;
a pull-back valve mounted to said second reservoir for removing a third amount of air and free moisture from said liquid adhesive in said second reservoir;
a vacuum box mounted to said slot die for removing a fourth amount of air and free moisture from said liquid adhesive prior to depositing said liquid adhesive to said base sheet; said vacuum box being mounted to said slot die in such a way for removing air and free moisture from a lower laminae of said liquid adhesive, and for removing air from said base sheet prior to depositing said liquid adhesive to said base sheet.
