Excellent results at Fridlington Farms
“Excellent results from first storage season at Fridlington Farms”

Results are in from the TaperStor we designed and constructed for Fridlington Farms in 2013, ready for their first storage season.

The last of the store was emptied yesterday, later than expected. Matthew Wallace, Farm Manager at Fridlington Farms says “We have been very impressed, not only was the storage one month longer than anticipated but we were very impressed with the weight loss. Considering we had a rot issue, and had to blow the crop more, we achieved a low 7.2% weight loss.”

He also comments that the crop was of good firm quality.

Fogging the store is simple with the CIPC contractor using a key to put the store into a fogging mode. On the first application we had looked at the airflow in the ducts across the store. Airflow was exceptionally even with less than a 5% difference anywhere. We had used 32g of CIPC to store potatoes until mid-June. Sprout control was excellent.

Contact us to get details of our innovative TaperStor and let us show you what impressive results and payback it can give you.

Store excels in difficult year
Despite a difficult storage year and a thin skin potato variety, a Norfolk store has received exceptional bonuses for VR 808.

"VR808 from the 2011 crop stored very well for nine months and suffered no store losses. VR808 were unloaded in early July 2012 looking good and consistently achieving high bonuses from Walkers. Over 400 tons came out of the store, achieving an average bonus equivalent to an extra three and a half tons per Hectare."

SBCSR tells store operators to be aware of air pressure...
Following 6 months of lobbying from Crop Systems on the subject of air flow combined with air pressure, we are happy to have had the following release from SBCSR.

Adrian Cunnington writes:

Sutton Bridge has had a number of enquiries lately regarding air flow rates in stores and I thought it might be useful to provide a short explanation of some of the terms that are regularly used in quoting ventilation capacities for potato stores.

Most commonly the rate of air delivery is quoted in a volume of air per unit time per tonne, for example 0.02 m3/second/tonne. Rates are also commonly quoted in continental Europe in m3/hour/tonne, which in this example is 72 m3/h/t (0.02 x 60 x 60). These figures are equivalent to the old imperial level of 40 cubic feet per minute per ton (cfm/t) which was more or less fitted as standard to British bulk stores which were built 15 years or more ago.

Since around 2000, there has been a trend towards specifying higher airflows to boost drying capacity. This has gathered pace most recently with the advent of affordable variable speed drives (also known as variable frequency drives or inverters) which allow flows to be lowered for the holding period. Rates in the region from 0.03 to 0.05 m3/s/t (60 - 100 cfm/t) are not unusual but, historically, these higher airflow rates have been more commonly used in mainland Europe and the Netherlands, in particular. Of course, higher airflow rates require larger fan capacities and ductwork.

The other important point when considering fan capacity is to be aware of the fan’s capability in relation to the system resistance to that air flow. Energy is lost in making air move faster, in negotiating bends in the air path and in overcoming system restrictions such as louvres or fridge coils. There should also be some important resistance provided by the lateral or floor outlets as these ensure an even distribution of air across the store. The final restrictions to flow come from the crop and are related to tuber size (smaller potatoes pack together more closely), loose soil content and even sprouting. All of this resistance is measured as static pressure and typically, for a 3.5 m pile of potatoes, the total static pressure will be somewhere between 100 to 400 pascals (Pa). The old imperial unit was inches (”) of water gauge (WG) and 250 Pa is roughly equivalent to 1” WG.

Typically, a safe design figure used for a bulk processing store will be 375 Pa. The system resistance may well be lower (and the airflow higher) in seasons when the crop is clean but it is when the potatoes are wet that performance becomes most critical. In contrast, in an overhead throw box store, the system resistance will be much less, typically under 100 Pa, as the air is not forced through the potatoes.

It is therefore not adequate, when comparing ventilation systems, to purely look at airflow figures if these are not qualified with a system resistance. If there is little or no resistance, the airflow will be much higher than if energy generated by the fan has to be consumed in overcoming a high level of static pressure. Fan performance varies enormously according to the design, blade angle, motor power and torque so it is important to get specialist assistance in choosing the correct fan for your store.
