Is there a standard ratio of warehouse size to truck approach area around it?
For a 3,000 sq. meters (some 27 thousand sq. feet) food processing plant, with a 10 thous. sq. ft. warehouse and a 60-Ton throughput of frozen meat per day - what would be the approximate needed lot area, to allow movement of 3 T. distribution trucks, 10-Ton delivery trucks, and some three semi containers per day, plus parking for 6 trucks and 20 cars.

There is no standard ratio of delivery space to building space. The requirements are dictated by the layout of the site, operational circulation, avoidance of conflict with other vehicles and pedestrains and the swept path required to turn vehicles to position them for parking/loading/unloading.
In the UK we refer to "DESIGNING FOR DELIVERIES" (DfD) published by the Freight Transport Association.
Parking bays are standard but I suspect that the UK standard would be undersized for the average US vehicle. A car parking bay in the UK is 2.4m x 4.8m unless for disabled drivers when it is 3.6m x 4.8m. The aisle should be 6m. Parrallel parking bays are 2m - 2.4m x 6m. Lorry bays for a large artic (semi?) would typically be 17m x 3m.
Although DfD is a good source of information we would normally check any layout with a swept path prediction program such as WINTRACK which is used within AUTOCAD.
Note that gradient of the turning area can affect the turning space. Typical grdients should be around 1/50 although 1/40 should be considered a maximum and 1/60 a minimum. Ensure that areas where vehicles park to load/unload are flatter (say 1/80) to prevent the load moving of its own volition. This is particularly important if the load is transported in wheeled pallets.
