Fresh Produce – the exotic fruits going exported

This time, I try to compile my literature study and field experience into a pocket step-by step fresh fruit processing and storing method:

After harvesting, there comes the processing. Material needed:

Plastic Trays for harvested fruits. Fruits must be 60% ripe

Chemical material for washing (fresh seal) and waxing

Foam net

Packing Procedure for a good sea-shipment:

Produce should have enough post-harvest life for the trip and for marketing at the destination.

Specify the carrying temperature in both Celsius and Fahrenheit scales.

Specify the flow rate of fresh air exchange.

Specify humidity, controlled or modified atmosphere treatments, or other special treatments if they are requested.

Select cargo, dunnage, pallets, blocking, and bracing so that the load covers the entire floor of the container and meets highway weight regulations.

Packaging using Carton Box / Corrugated box

Carton dimensions

Pineapple:

1. Inner: 460mm x 370mm x 130mm

Outer: 500mm x 400mm x 170mm

Thickness of materials for boxes: S/F M x 2 125 E/F

2. Inner: 460mm x 370mm x 150mm

Outer: 500mm x 400mm x 210mm

Thickness of materials for boxes: S/F M x 2 125 E/F

Mango

1. Sweet Fragrance (in 4.2 kgs netto packing @400grams/piece)

Outer: 400mm x 300mm x 95mm

Thickness of materials for boxes: K300 x M150 x M150 + DC 310 gr

2. Alfonso (in 5kgs netto packing @200grams/piece)

Outer: 460mm x 270mm x 90mm

Thickness of materials for boxes: K300 x M150 x M150 + DC 310 gr


Stacking the boxes for cold-storage

· The pallet uses two-way entry and non reversible. Standard pallet size is 120cm x 100cm, made of mixed wood (fruit trees wood, Albasia wood). A tailor-made pallet can be ordered at Tangerang area at cost of c.a. IDR 30,000 from a good quality wood.

· A 40’FT CA container could load 20 pallets.

· Pallet must be firm enough so that it does not shift in handling or transport. The pallet will be unitized (tied together with net wrapping or corner braces and banding).

· Boxes should extend to the edge of the pallet. Free space at the periphery will allow the load to shift in transport.

· Align box vents between layers of boxes.

· Use pallets where deck board spacing aligns with box vents.

· Pallet should enable box corners to be well supported by deck boards. If not well supported, boxes will fail and allow produce to be crushed.

· Nominal outside box dimensions should allow for panel bulge and variation in box placement on the pallet. Do not stack boxes beyond the edge of the pallet.

The Corrugated boxes should be strong enough to withstand the effects of high humidity in storage and transport because the box normally loses strength over time when it is supporting a load.

Boxes and inner packaging should allow vertical airflow, especially if produce is warmer than refrigeration set point temperature when stowed.

Box venting also reduces box strength. Box vents should be located away from the vertical edges of the box and generally should not account for more than 5 percent of the box wall area. Boxes with greater than 5 percent venting must be specially designed to provide adequate strength. Box should have at least a 3 percent venting area on top and bottom panels. Box also has vents on the side panels to allow initial cooling. These allow air to flow horizontally to find open vertical venting if top or bottom vents are blocked by pallet deck boards or packaging materials.

– Vents on horizontal box edges (sometimes called shoulder vents) are less likely to be blocked by produce or packaging materials than vents that are more toward the middle of panels. Vents for vertical and horizontal airflow should align when boxes are register-stacked or cross-stacked. Interior packaging and pallet deck boards should not block airflow through box vents

Different kinds of produce shipped together in one container should have compatible

– temperature needs

– ethylene sensitivity

– relative humidity needs

– modified or controlled atmosphere requirements, if used

– odors or chemical treatments

– airflow characteristics.
