Description

Mo a ri.n fryer tern eraS we The present invention relates to a method of monitoring the temperature of a fryer and to a temperature probe.
A number of foodstuffs are produced by a flying process in which the foodstuffs are conveyed along a fryer containing a body of heated oiL Many snack foods, such as potato chips, are produced using such a frying process. The frying parameters can vary along the product flow path and also across the product flow path. For example, the oil temperature can vary along the flow path, or transversely across the flow path at any given longitudinal location. Such frying parameters may vary as a result of a variations in the oil heating apparatus, andj'or variations in the properties of the input foodstuffs to be fried. Any uncontrolled or undetected variations in the flying parameters can lead to nonunifbrm products.
In a fryer, one primary frying parameter which may have a arge impact on product quality is oil temperature. It is known to use fixed temperature sensors,in a flyer to monitor the production process. However, these sensors are laborious to install and provide rather limited infoimation on the temperature profile of the oil in the flyer, and the temperature to which the products are subjected during the frying process.
For some industrial fryer applications, it is desirable to model or simulate the frying process using software. However, an accurate representation of the flying process requires accurate input data, for example the temperature profile along the flyer, and option ally across the fryer. Existing fryer temperature monitoring systems provide inadequate data for fully simulating the temperature variations to which the products are subjected during the frying process in any given fryer.
It is an aim of the present invention to provide a method of monitoring the temperature of a flyer, and to a temperature probe which may be used in such a method, which is easy and inexpensive to install and provides a very versatile device for measuring temperature within the fryer at various locations.

The transmissions are receiver by a receiver and recorded.
Tl.e temperature probe 2 has a density of no more than 925g/dm3. This provides that the temperature probe 2 can float in an edible oil which is typically used for frying, for example sunflower oil which is used for frying many snack.thods such as potato chips and has a specific gravity of about 920g1dm3.
The temperature probe 2 can be used in a method of monitoring the temperature of a flyer.
Referring to Figure 3, in the method, the fryer 50 contains a body of heated oil 52. Typically, the temperature sensor 4 is adapted to measure a temperature of at least 200°C and the heated oil 52 is at a temperature of at least 200°C.

The foodstuffs 5$ may comprise snack foods, for example potato chips The temperature probe 2 is disposed in the fryer 50 so as to he ithin the body of heated oil 52. Since the density of the temperature probe 2 is lower than the specific gravity of the oil 52, the temperature probe 2 floats on the surface of the oil 52. The temperature probe 2 is floated on the oil 52 along at least a part of the product flow path 60 of the fryer 50, The temperature probe *4 is conveyed together with the foodstuff 58 a'ong the product flow path of the fryer 50 during the foodstuff frying process. A temperature profile corresponding to the temperature sensed by the. temperature sensor 4 of the temperature probe 2 along the respective part of the product flow path 60 is recorded. The flyer 50 includes conventional conveying apparatus 62, such as a helical screw, paddles, flights, etc. to convey the product through the fryer 50.
The temperature probe 2 may he floated a!ong a selected longitudinal flow path 64 at a selected transverse position relative to a centre line 66 of the product flow path 60.
A plurality of temperature values sensed by the temperature sensor 4 over a period of time is transmitted by the wireless transmitter 26 within the casing 6. The transmissions are received by a receiver 63 a.d recorded to provide a temperature profile along the fryer 50.
Typically, the wireless transmitter 26 transmits series of wireless signals in step (iv), each wireless signal including information associated with a respective temperature value sensed by the temperature sensor 4, to provide a series of temperature values associated with the respective part of the product flow path 60.
By providing a temperature probe 2 which can float in the flyer oil and is dimensioned so as to be substantially the same size as the foodstuff being flied, the temperature probe 2 is able to follow the path taken by products through the fryer, including floating on the surface of the oil and being temporarily partly or wholly submerged in the oil when urged downwardly by any conveying apparatus in the fryer, and thereby provide a substantially continuous temperature profile which is actually experienced by the foodstuff during its passage through the fryer.
